m-psk modulation and de modulation

Gold序列是基于m序列优选对产生的，是由两个长度相同、速率相同、但码字不同的m序列优选对模2加后得到的，一对长度为N的m序列优选对可以产生N＋2条Gold码。(Gold sequence is based on the optimization of m sequences generated by both the length of the same, the same rate, but different m codeword sequence optimization of mode 2 increases obtained, a pair of length N of the m sequence optimization can generate N 2 Article Gold code.)

该程序绘制了仿真信号的FFT频谱和功率谱，并调用emd分析方法，绘制了emd分解结果，以及瞬时包络和瞬时频率图，还有Hilbert-Huang谱和Hilbert边际谱。(Program to draw the FFT spectrum of simulation signal and power spectrum call the emd analysis method, drawn emd decomposition, as well as instantaneous envelope and instantaneous frequency plot, there is the Hilbert-Huang spectrum and Hilbert marginal spectrum.)
