Matlab实现QPSK和16-QAM的仿真，绘制信号散点图及相应时域波形图-Matlab realization of QPSK and 16-QAM simulation, rendering the signal scatter and the corresponding time-domain waveform

This project is simulation of the MQAM modulation in the MATLAB. this project has one file for Modulating some random number and one file for demodulating of the signal. just run the first code and after that run the second code. this code also has

This project is simulation of the MPSK modulation in the MATLAB. this project has one file for Modulating some random number and one file for demodulating of the signal. just run the first code and after that run the second code. this code also has

This project is simulation of the 2FSK modulation in the MATLAB. this project has one file for Modulating some random number and one file for demodulating of the signal. just run the first code and after that run the second code. this code also has

实现的是原模图LDPC码的散点图以及BER参数测量(The scatter plot of LDPC code and the measurement of BER parameters are realized.)
