摘　　要：PCMA理论上可将现有的卫星通信容量提高一倍。文中对Simulink仿真模块参数进行设定,搭建键控法的二进制相移键控(binary phase shift keying,BPSK)模型和调相法的正交相移键控(quadrature phase shift keying,QPSK)模型,以及基于BPSK和QPSK的频带传输的PCMA通信系统仿真,分析了自我信号复制模块中的时延估计算法。仿真结果验证了理论的一致性。PCMA theoretically existing satellite communication capacity doubled. This module parameters are set Simulink simulation, set the binary phase shift keying keying modulation for the model and the quadrature phase shift keying model, and based on BPSK and QPSK transmission PCMA band communications system simulation, analysis of self-replication module signal delay estimation algorithm. The simulation results verify the theoretical consistency.
