本程序主要分析了三种调制方式对放大器非线性的敏感度，从中得出结论，APSK信号最佳。-the procedures of the three main methods of modulation of the nonlinear amplifier sensitivity, draw conclusions, APSK best signal.

实现了pcm调制的全过程的MATLAB仿真，包括调制、A率压缩、量化、解扩、解调、信号恢复。-Modulation achieved pcm MATLAB simulation of the whole process, including the modulation, A rate of compression, quantization, despreading, demodulation and signal recovery.

使用matlab进行通信信号调幅、单边带、双边带信号的调制与解调。-modulation and demodulation of AM、DSB、SSB

基于matlab的BPSK信号的基带调制解调，利用码元周期内信号与载波的积分来进行解调，适合新手熟悉matlab-Matlab-based baseband BPSK signal modulation and demodulation, the use of the symbol period signal and integrating the carrier demodulation, suitable for novice matlab familiar
