PCM编码解码matlab 代码

实现了QPSK的调制，使用了ise自带的dds的IP核(QPSK is modulated and the IP core of DDS is used in ise.)

利用DML算法和SML算法实现到达方位角的估计(Estimation of arrival azimuth using DML algorithm and SML algorithm)

实现16QAM完整的调制解调系统，包括基带信号串并转换，星座图映射，升抽样成形滤波，升采样半带滤波，数字上变频，功放的多项式非线性效应，加性高斯白噪声信道，接收端下变频，降采样，匹配滤波，绘制接收端星座图。(16QAM modulation and demodulation realize the complete system, including the baseband signal string and conversion, constellation mapping, sampling shaping filter liter, half liter sampling with filtering, digital up-conversion, amplifier polynomial nonlinear effects, additive white gaussian noise channel, the receiver end down-conversion, down-sampling, matched filtering, draw the receiver constellation.)

本程序是对低密度奇偶校验码的校验矩阵的源程序，相信会对研究ldpc码的人会很有帮助的(This procedure is a low-density parity check matrix of code source, I believe that research on LDPC codes will be very useful)

说明：  单模光纤中相干接收QPSK信号应用了CMA算法的简单DSP示例，自带vpa仿真数据。(A simple DSP example of CMA algorithm is used to receive QPSK signals coherently in single-mode optical fibers, with VPA simulation data.)

一个很小和天线计算程序,我觉得非常实用,发上来与大家分享()
