Description
(54) УСТРОЙСТВО ДЛЯ ПЕРЕДАЧИ И ПШЕМА ИНФОРМАЦИИ(54) DEVICE FOR TRANSFER AND INFORMATION
Устройство работает следующим образом.The device works as follows.
Or источ шка I сигнал поступает в канал св зи 3 через иредыскажающий фильтр 2 с регулируемой передаточной функцией, с выхода которого одновременно сигнал подаетс на вход анализатора спектра 6. На гтриемник 5 сигнал поступает с канала св зи 3 через корректирующий фильтр 4 с регулируемой передаточной функцией.Or the source I signal arrives at link 3 through an adjustable-relief filter 2 with an adjustable transfer function, the output of which simultaneously sends a signal to the input of the spectrum analyzer 6. At the receiver, signal comes from link 3 through an adjusting filter 4 with adjustable transfer function .
На выходе анализатора спектра 6 формируетс сигнал, пропорциональный eJшчинe отклонени мгновенного энергетического спектра предыскаже ного сигнала от заданного энергетического спектра оптималыюго 11редыскаже1шого сигпэла. Изменение мгно е1шого энергетического спектра синала на выходе предыскажающего фильтра 2 приводит к изменению сигнала на выходе аишшзатора спектра 6. В соответствии с этим сигналом измен ютс , передаточные функции предыскажающе|-о фильтра 2 и корректирующего фильтра 4. При этом на выходе 1федыскажающего фильтра 2 энергетический спектр вновь принимает вид спектра ошимально преды скаженного сигнала, а на выходе корректирующего фильтра 4 сигнал полностью восстанавливаетс .At the output of the spectrum analyzer 6, a signal is formed that is proportional to the amount of deviation of the instantaneous energy spectrum of the predistortion signal from the specified energy spectrum to the optimum 11 sigpele. A change in the instantaneous energy spectrum of the synal at the output of the predistortion filter 2 leads to a change in the signal at the output of the a downshift of spectrum 6. According to this signal, the transfer functions of the predistinctive | the spectrum again takes the form of the spectrum of the predicted signal, and at the output of the correction filter 4, the signal is completely restored.
Предложенное устройство позвол ет автоматизировать оптимизацию предыскажени передаваемого и соответствующего корректировани принимаемых сигналов и повысить помехоустойчивое ь устройства.The proposed device allows one to automate the optimization of the distortion of the transmitted signal and the corresponding correction of the received signals and to increase the noise immunity of the device.
