Abstract

The carrier signal is subject to interference and attenuation in the channel transmission process. In this paper, a high-performance anti-interference method for the modulation and demodulation of phase modulation QDPSK signals is proposed, and the programming and waveform simulation of the QDPSK system are conducted based on an analysis of the module. In addition, good modulation and demodulation effects are achieved in the waveform experiment, indicating the correctness and practicality of the QDPSK system.
