Nakagami信道产生的代码，大家经常能用到的程序

实现信号处理中QAM调制、过信道、解调部分。其中QAM调制部分可改符号点数，M阶数，信道加高斯白噪声、时延、多径，调制解调均有星座图。通过本代码，可学习QAM调制解调，或者通信系统的知识。(To achieve QAM modulation, signal processing over channel, a demodulation section. QAM modulation section can be changed symbolic points M order channel additive white Gaussian noise, delay, multipath, the modem has constellation diagram. QAM modulation and demodulation, or communication system knowledge through this code, you can learn.)

说明：  原始信号加载高斯白噪声和椒盐噪声后用维纳滤波器滤波(The original signal was loaded with White Gaussian noise and salt noise and then filtered by Wiener filter)

用fft算法求信号函数的相位或相位差，发现一些规律，对正弦、余弦函数而言，所得结果，有差异( a simulationg of using fft algorithm measuring phase and some problems)

说明：  完整的GPS信号捕获过程仿真-matlab，完整的GPS信号捕获过程仿真-matlab(A complete GPS signal acquisition process simulation-matlab, a complete GPS signal acquisition process simulation-matlab)
