DETAILED DESCRIPTION U? THE INVENTION The Eigure i illustrates a complete block of words i and part of a successive block of words z, received in standby mode by the receiver of a transceiver, particularly a mobile telethon station, in a D-AMPS AMPS OR system. 1AOS. A block of words consists of a sequence of puxiLob Do (S j of i? inu, uud be uen xd ue word synchronization ws (SP) of li bits and five repetitions of words for a station to mobile phone A and five repetitions of words for a mobile phone station, each word repetition contains 4U bits, including a parity field, if a mobile station has a subscriber. Ei uai, - in the aia ras i bio, and five repetitions of the word Al for a station of tpn tnnn moved A. and nnm rpppp pons dp palahras Kl for a mobile phone station. Only the first repetition of the word A and the first repetition of the word tí'Z are shown for the mobile telephone station A and the mobile telephone station, respectively, in the Eigure z which is a schematic block diagram. of the receiving portion of a tel station mobile effect, one defines a receiver that has an input IN, z defines a decoder to aecoditicate the data received by the receiver i, i defines a word synchronization detector, 4 defines a counter, b defines a clock generator and b defines a a microprocessor by means of the diagram and picture of J and the time diagrams in Figures 4A and 4t, are you now ebcxxbxid the iuinx? udiuxeuL? from id p? x x? n xecepu? xd in xd Eigura Z. the step the process starts when the power of the receiver i is connected. In the JUI step the receiver i is tuned to an emission control channel (EüCC), and in step? Z the clock generator five of the Eig z z is ü of ah I ano oo 'cnc * t X r * a -_, the speed of the chronometer pulses generated by the five-digit filter will track the speed of the bits of the block of words that enter when they are derooted, in the order of the radius. In the step JU the word synchronization is performed by means of the word synchronization detector J. Word synchronization takes place in the word synchronization sequence s of a block of words, for example the block of words i of Eigure i. In the step JU, the repetition i of a word of a block of words is received, for example the word Ai of the block of words i of Figure i. The repetition i of the word Ai of the word block i is received by the microprocessor b from the decoder z as indicated by the double line line in Figure z. In the step JU the microprocessor b performs an operation aecoairicacion ¿sin ai receive xa repetition i ae the word AI. The operation of aecoaificacion tíCH is well uuii ciud in ebLe u? IaexLU and, in ibeibe uen xd n? I will write more. In the step JUb, the pariaaa, aepvaaa in the step JUb from the parity field of the received repetition i, is checked to verify a correct reception of the repetition i of the word AI of the block ae words i. In the step JU, the number of inactive bytes is calculated between the last repetition of the repetition of the block of words i and the first byte in the repetition of the digit A7, rtpl hl qpp rtp n lahras 7. In the Jütí step the clock generator five is set to the autonomous mode, and at the same time the receiver i is disconnected in the step. -uy by means of the microprocessor b. Since the i receiver is disconnected, the chronometer pulses generated by the clock generator b in the autonomous mode correspond to the bits that must have been received, the receiver having been disconnected. These chronometer pulses are counted in counter 4 which informs microprocessor b of each "inactive byte" counted in step Jiu. In step Jli the microprocessor b verifies if an "inactive byte" emitted by the counter 4 is the last "inactive byte" as it was registered in step JU /, and the answer is "yes", does the microprocessor fo turn on ex xeuepL? xi in the pdbu, - >; i &dx iiixbuu Ixemp? in the u jij the clock generator b is set to the tracking mode again to receive the repetitions i of the word KZ from the word block z, whereupon the processor returns to step JU4 of Figure J. If the parity of the repetition i of the word KZ of hl? rtna /? < a na 1 a n n a s V o c * (M? C? tt -_. v t X i f 'a? n a I n c? JUb, the receiver i will again be disconnected in the Juy step. In this way, as it is evident to remove from Fioxira 4a, the receiver i in a mobile teleton station A will be displayed during the renpfipon of a nalahra A in each block of words. The same is valid for a mobile telethon station which will be on only during the repetition of a word ü in each block of words. Consequently, the effect of energy reduction í? it's the same for both mobile phone stations A and you. If, in step JUb, the parity of the repetition i of a word in a block of words is not OK, the rest of the repetitions of this word in the block of words will be received in step J14, which in step Jib a word synchronization has to be performed again by means of the word synchronization detector J. In step J14, when the rest of the repetitions have been received from the same country, an important decision is made and the operations of aecoditication bCii and cuiupiu iun de pdii? du en und x? xiud cunven x? iidi.

After word synchronization has been performed in step Jib, in step -Jw the repetition i of a word of the successive block of words is received and the process continues as described above. According to the invention, the inactive time is sequences of bits and word synchronization of the c i mn pn r p h l nrp ip rl na l a ra s. P S dpr- i r. P I re¡r < t > - r? - I c; p connects exactly at the moment of receiving the first rpt? pt? r? nt? dp nalahra P? PI l na? P dp na barks successive. I) P this way, the inactive time is equal to the theoretical maximum between the repetitions of words of equal number in two blocks of successive words. By means of the invention, resynchronization for the received data stream is avoided, after tuning for an emission control channel and the initial use of the word synchronization sequence. This reduces the risk of false detection of word synchronization after the inactive periods, which can happen if the inactive time was different from that described in the previous one. In step JU4 of Figure J, it is not absolutely necessary to receive the first repetition of a word in a block of words and carry out the rest of the process in xeidux? N with ebLd pxxiuexd p Lx xun. From iie ii ?, in Le? Xxd it is possible to select any of the five repetitions in step U that will be received and executed through the process based on this selected repetition. However, if in step JUb it is found that the parity of the selected received repetition is not OK, rn p vi -a, most of them can be received. In this way, in practice, the first repetition of one. Oa.ia.bra of a Qrru of osiiD dS must be received. So my mo, in the naso .i () b, if the delivery rp npmpra repetition of words is found to be not OK, in step S14 can only receive the second repetition instead of all the repetitions z-s. In this case, the decoding operation tíCH of the Süb step would have to be performed in u this second repetition. If when checking the parity in step 306 is OK for this second repetition, the process will continue at step 307 by calculating the number of "inactive bits" from this second repetition for the first repetition of the next block of words SU ebx vu.
