This m-file simulates MPSK (theoretical and simulated) with Gray coding
This m-file simulates MPSK (BPSK,Qpsk,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using Qpsk and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).
提取信号七个基于瞬时信息的特征：零中心归一化瞬时幅度功率谱密度的最大值,零中心归一化瞬时幅度绝对值的标准偏差，零中心非弱信号段瞬时相位非线性分量绝对值标准偏差，零中心非弱信号段瞬时相位非线性分量标准偏差，零中心归一化的非弱信号段瞬时频率绝对值的标准偏差，一个信号段的归一化瞬时频率功率谱密度的最大值，根据信号 Qpsk 和16QAM在 XI 轴投影的不同表现，提出特征参数。
