QAM PSK 信号的调制星座图代码,实现调制信号的星座图显示和比较-the code of QAM&PSK Signal modulation constellation diagram

直接信号扩频的原理是利用一个有周期的伪随机的码序列去调节原始的信号，并用调制的信号区改变载波的相位的方式。-The principle of direct spread spectrum signal is the use of a cycle of pseudo random code sequence to adjust the original signal, modulation and signal area change the way of carrier phase.

旨在仿真OOK信号，这是国家重大项目的一个子课题，编译程序验证(Designed to simulate OOK signals, which is a sub task of national major projects, compiler verification)
