In the current level of technology, no sources of information have been identified that would contain information about objects of the same purpose with the indicated set of distinctive features, which allows us to consider the SPPI of the present invention new and having an inventive step.

, из n-й группы источников информации, где

, в том числе, при необходимости форматируют в цифровой поток, не обязательно одинаковым образом с форматированием информации источников из других групп. Цифровые потоки тактово синхронизируют и упорядочение осуществляют, например, последовательно по k от 1 до K_n, одновременно за такт длительностью T считывание двоичных цифр K_n синхронизированных бинарных цифровых потоков. При необходимости их шифруют. Полученные таким образом M_n-арные символы, где,

, преобразуют в n-й поток M_n-арных сигналов, соответствующих M_n-арным символам. Передают эти сигналы через канал передачи, совместимый с передаваемыми сигналами. При тактово синхронизированном приеме конкретного M_n-арного сигнала за такт длительностью T получают M_n-арные символы и соответствующие K_n синхронизированные бинарные цифровые потоки. Упорядочивают их как при упомянутом считывании. При необходимости дешифруют и форматируют цифровой поток в поток информации, не обязательно одинаковым образом с форматированием информации источников из других групп. Информацию подают к соответствующему потребителю информации. Перед передачей и после приема осуществляют при необходимости множественный доступ синхронизированных потоков M_n-арных сигналов, в том числе других групп источников информации. Кроме того, при необходимости передают по крайней мере по одному дополнительному каналу передачи по крайней мере информацию об опорных уровнях M_n-арных сигналов.The essence of the method is as follows. Information of each k-th information source, where

, from the nth group of information sources, where

including, if necessary, formatting into a digital stream, not necessarily in the same way with formatting information of sources from other groups. Digital streams are synchronized clockwise and ordering is carried out, for example, sequentially in k from 1 to K _n , at the same time, for a cycle of duration T, the binary digits K _{n of} synchronized binary digital streams are read. If necessary, they are encrypted. Thus obtained M _n -ary symbols, where,

are converted into the nth stream of M _n -ary signals corresponding to M _n -ary symbols. These signals are transmitted through a transmission channel compatible with the transmitted signals. With clock-synchronized reception of a specific M _n -ary signal per cycle duration T, M _n -ary symbols and corresponding K _n synchronized binary digital streams are obtained. Arrange them as in the aforementioned reading. If necessary, they decrypt and format the digital stream into the information stream, not necessarily in the same way as formatting the information of sources from other groups. Information is supplied to the relevant consumer of information. Before transmission and after reception, if necessary, multiple access of synchronized streams of M _n -ary signals, including other groups of information sources, is performed. In addition, if necessary, transmit at least one additional transmission channel at least information about the reference levels of M _n -ary signals.

. Общее количество символов равно

. При этом обеспечивают заданное упорядоченное взаимно однозначное соответствие этих символов с подгруппами. В подгруппах же обеспечивают взаимно однозначное соответствие с вариантами битов в каждой подгруппе. Кроме того, формируют M_l,n-арные сигналы с общим количеством, равным общему количеству M_l,n-арных символов, с одной одинаковой огибающей для всех сигналов в подгруппе. Обеспечивают ортогональность их огибающих и заданное упорядоченное взаимно однозначное соответствие подгрупп сигналов с огибающими, а в подгруппах обеспечивают взаимно однозначное соответствие вариантов символов с вариантами сигналов. Варианты сигналов отличаются друг от друга не обязательно, но, например, вариантами фазовой манипуляции несущей, количество которых задано равным количеству вариантов символов в подгруппах. Затем формируют конкретный M_n-арный сигнал в виде совокупности конкретных M_l,n-арных сигналов, соответствующих конкретным M_l,n-арным символам и совместимых с каналом передачи. Их передают совместно одновременно, преимущественно с одинаковой энергией, за такт длительностью T. При приеме выделяют конкретные M_{l, n}-арные сигналы из переданной за такт длительностью T их совокупности и получают конкретные M_l,n-арные символы. Выделяют в каждой подгруппе соответствующий вариант из kx_l,n битов и восстанавливают по полученным вариантам заданным образом конкретную группу из K_n битов.The technical result, which consists in increasing the technical and economic efficiency of the SISP, is achieved due to the fact that after reading the binary digits K _{n of the} synchronized binary digital streams, the nth group of the received K _n bits is divided in a given ordered manner into l-th subgroups, where l can vary from 1 to L. The number of bits in each subgroup is kx _{l, n} , and the sum of kx _{l, n} is K _n . Next, M _{l, n} -ary symbols are formed with the number of symbols in the l-th subgroup equal to

. The total number of characters is

. At the same time, they provide a given ordered one-to-one correspondence of these symbols with subgroups. In the subgroups, they provide a one-to-one correspondence with the bit options in each subgroup. In addition, they form M _{l, n} -ary signals with a total number equal to the total number of M _{l, n} -ary symbols, with one identical envelope for all signals in the subgroup. Ensure the orthogonality of their envelopes and the specified ordered one-to-one correspondence of the subgroups of signals with the envelopes, and in the subgroups provide a one-to-one correspondence of symbol variants with signal variants. Variants of signals differ from each other not necessarily, but, for example, by variants of carrier phase manipulation, the number of which is set equal to the number of symbol variants in subgroups. Then form a specific M _n -ary signal in the form of a set of specific M _{l, n} -ary signals corresponding to specific M _{l, n} -ary symbols and compatible with the transmission channel. They are transmitted together simultaneously, mainly with the same energy, per cycle of duration T. When receiving, specific M _{l, n-} ary signals are extracted from their set transmitted per cycle of duration T and receive specific M _{l, n-} ary symbols. In each subgroup, a corresponding variant of kx _{l, n} bits is selected and a specific group of K _n bits is restored according to the obtained variants in a predetermined manner.

To organize work and improve the reliability of the method, it is advisable to transmit information about the reference, for example, single, levels of M _n -ary signals. It can be transmitted, for example, after several clock cycles on the main channel. However, in some cases it may be appropriate to use an additional channel to transmit this and other information. In addition, if it is necessary to separate sequentially transmitted signals, including for extracting reference signals, the transmission and reception method interrupts signal transmission in at least one of the separation clocks between the separated signals.

The issues of timing and synchronization during transmission and reception are solved by any well-known methods and means of the prior art, for example, in the same way as in the analogue.

The division of the group in the proposed way into subgroups significantly increases the efficiency of the transmission and processing of information during its recovery. At reception, the restoration of this group is greatly simplified, since it is performed in stages for subgroups with a significantly smaller number of options for each, and a specific group of K _n bits is restored in a predetermined manner from the initially restored subgroups.

. Также в соответствии с формулой изобретения при необходимости, используя множественный доступ, можно осуществить передачу по одному каналу N групп из K_n источников информации в каждой. Например, в простом случае с числом групп N=10 и с 20 источниками информации в каждой группе по одному каналу можно передать информацию от 200 источников.The following simple example illustrates the capabilities of the proposed method. We transmit the information contained in K _n = 20 bits in the cycle M _n -ary signal. In accordance with the claimed method, a group of K _n bits in a predetermined manner is divided into subgroups. Namely, 6 subgroups containing 3 bits and 8 variants each were selected, and one subgroup with 2 bits and 4 variants (52 variants in total). The sum of the bits of all subgroups is K _n = 3 × 6 + 2 = 20. In the group of K _n = 20 bits, the total number of possible options (the number of required M _n -ary signals) is

. Also, in accordance with the claims, if necessary, using multiple access, it is possible to transmit through one channel N groups of K _n information sources in each. For example, in the simple case with the number of groups N = 10 and with 20 sources of information in each group, one channel can transmit information from 200 sources.

The present invention is useful in that it can be practically applied to develop and improve any communication system with any organization of its work, for example, already using well-known multiple access methods and well-known signal processing methods.

Industrial applicability. The present invention can be applied in SPPI in any communication systems. SPPI according to this invention allows efficient use of the resource and can work simultaneously with a large number of heterogeneous information. The analysis made it possible to establish: analogues with a set of features identical to all the features of the claimed technical solution are absent, which indicates the conformity of the claimed method to the “novelty” condition. The results of the search for known solutions in the field of API for the purpose of identifying features that match the distinctive features of the prototype of the claimed method showed that they do not follow explicitly from the prior art. Therefore, the claimed invention meets the condition of patentability "inventive step".
