Аннотация

The algorithm for generating and processing signals with linear frequency modulation (LFM) called Reduced Set is considered. It is shown that signal processing in the Reduced Set algorithm can be improved. A modified Reduced Set algorithm is proposed, which enhances the probability of correct demodulation of symbols in the presence of multipath propagation, as well as timing and frequency offset. Under these conditions, the proposed algorithm demonstrates a reduction in the probability of a bit error by more than 3 orders of magnitude compared to the classical Reduced Set algorithm processing approach.
