qpsk 高斯白躁信道下的相位调制仿真，帮助初学者理解消化，有很大作用-please pay attention to the simulation, it will help you to begin the study of it

OFDM通信系统调制解调 包括数字前端处理、卷积编码、峰均值抑制、符号定时、频偏检测、信道估计、相位补偿等-OFDM modulation and demodulation communication system including digital front-end processing, convolution coding, the mean peak inhibition, symbol timing, frequency offset detection, channel estim

实现QPSK调制，采用两种方法相位选择法和I/Q两路相加法-QPSK modulation using two phase selection method and I/Q two-way additive method
