考虑了多进制位置相移键控（MPPSK）信号的解调及抗干扰问题。提出了一种利用特殊冲击滤波器输出信号的MPPSK解调器的新型匹配滤波方案。通过相干处理和带通滤波滤除干扰，然后将输出波形送入匹配滤波器（MF）进行解码。将基于匹配滤波器的MPPSK解调器的仿真结果与传统的自适应阈值积分鉴别解调方案进行了比较。仿真结果表明，具有码间抗干扰性能的解调优于现有的主流解调方案。
The problems of m-ary Position Phase Shift Keying (MPPSK) signal demodulation and anti-interference were considered. A novel matched filtering scheme of the MPPSK demodulator which used output signal of the special impacting filter were proposed. The interference was filtered out by coherent processing and band-pass filtering, then the output waveform was put into the matched filter (MF) to decode. The simulation results of the MPPSK demodulator based on the MF, was compared with the traditional adaptive threshold integral discrimination demodulation scheme. The simulation results indicated that the demodulation with inter-symbol anti-interference performance was better than the existing mainstream demodulation schemes.
