Abstract
Способ символьной синхронизации при приеме сигнала кодоимпульсной модуляции - фазовой манипуляции с известной структурой, основанный на определении границ двоичных символов кодовой последовательности и демодуляции принятых информационных символов, отличающийся тем, что процесс символьной синхронизации осуществляют в частотно-временной области с применением контура двухуровневой обработки сигнала, использующего алгоритм расчета спектральной плотности мощности дискретизированного радиосигнала, где, на первом уровне обработки осуществляют поиск границ двоичных символов, основанный на вычислении коэффициентов корреляции спектральных образов с эталонным спектральным образом границы символов «01», вырабатывают строб-сигналы, подаваемые на инерционный генератор символьной частоты, а на втором уровне обработки сигнала осуществляют демодуляцию двоичных символов на основе вычисления коэффициентов корреляции спектральных образов, получаемых после вычитания из принимаемого символа опорного сигнала с эталонным спектральным образом символа.A method of symbol synchronization upon receipt of a code-pulse modulation signal — phase manipulation with a known structure, based on determining the boundaries of the binary symbols of the code sequence and demodulating the received information symbols, characterized in that the symbol synchronization process is carried out in the time-frequency domain using a two-level signal processing circuit using an algorithm for calculating the spectral power density of a discretized radio signal, where, at the first level of processing they search for the boundaries of binary symbols based on the calculation of the correlation coefficients of the spectral images with the reference spectral image of the symbol boundary “01”, generate strobe signals supplied to the inertial symbol frequency generator, and at the second signal processing level, demodulate binary symbols based on the calculation of the correlation coefficients spectral images obtained after subtracting from the received symbol the reference signal with the reference spectral image of the symbol.
