Анализ М-последовательностей многозначных символов

Abstract

Проанализированы периодические функции корреляции псевдослучайных сигналов на основе М-последовательностей символов с основанием не равном 2 и показана полезность использования этих сигналов при передаче информации в условиях сильных помех при их корреляционной обработке.

In clause the references to the programs, developed by the authors, of a finding of pseudo-casual signals constructed on /W-sequences of symbols with the basis, not equal 2 are given. These programs allow to expand ensemble of known /W-sequences and give additional opportunities to the developers of channels of communication with correlation reception of the information. Two features are found by way of reception of periodic functions of correlation for figurative and пятеричных of /W-sequences as against binary /W-sequences. The analysis of periodic functions of correlation of pseudo-casual signals constructed on /W-sequences of symbols with the basis, not equal 2 is spent, and the opportunities of these functions are confirmed to have the greatest possible ratio signal/noise, which was earlier known for binary symbols. It allows to make a conclusion about expediency of use of multiple-valued /W-sequences in transfer of the information in conditions of strong handicapes at their correlation processing.
