The need to increase the transmission rate of discrete information in modern single-frequency communication systems requires joint phase and amplitude shift keying of the transmitted signals. Thus, this paper is focused on addressing a coherent demodulation of APSK signals and incoherent ADPSK and DAPSK signal processing. To demodulate DAPSK signals, it is proposed to use the logarithmic ratio of the neighboring symbol amplitudes. The estimates of the interference immunity of the signals under consideration have been obtained, and statistical simulation has been carried out. After the following comparative analysis of the examined signals, the conclusion can be drawn that the research results are fully applicable and useful for the design and development of demodulators and different communication systems. #COMESYSO1120.

摘要

The need to increase the transmission rate of discrete information in modern single-frequency communication systems requires joint phase and amplitude shift keying of the transmitted signals. Thus, this paper is focused on addressing a coherent demodulation of APSK signals and incoherent ADPSK and DAPSK signal processing. To demodulate DAPSK signals, it is proposed to use the logarithmic ratio of the neighboring symbol amplitudes. The estimates of the interference immunity of the signals under consideration have been obtained, and statistical simulation has been carried out. After the following comparative analysis of the examined signals, the conclusion can be drawn that the research results are fully applicable and useful for the design and development of demodulators and different communication systems. #COMESYSO1120.
