MATLAB编写的采用二相键控扩频通信仿真程序-MATLAB prepared by the two phase shift keying using spread spectrum communications simulation program

基于matlab的QAM调制与解调。正交振幅调制（QAM）是一种幅度和相位联合键控（APK）的调制方式。它可以提高系统可靠性，且能获得较高的信息频带利用率，是目前应用较为广泛的一种数字调制方式。 -Matlab based on the QAM modulation and demodulation. Quadrature amplitude modulation (QAM) is a joint amplitude and phase keying (APK) modulation met
