接受分集中采用选择式合并的函数，输出误码率和信噪比曲线(Acceptance of centralized using selective merge function, the output is bit error rate and SNR curve)

PCM编码译码的matlab代码，设一个输入量，对其进行通信原理仿真。(The MAT code of the PCM code decoding, set an input quantity, and simulate the communication principle.)

说明：  利用锁相环来实现MSK信号的定时同步，采用的是gardner算法(Using phase-locked loop to achieve timing synchronization of MSK signal, Gardner algorithm is adopted.)

这是矩阵计算一书的第二部分，由于是从网上下载的，两部分是分开的，没法合并，所以只好分两次上传，欢迎下载浏览。(This is the matrix of the second part of the book, as it is downloaded from the Internet, the two parts are separated, can not be combined, so only two upload, please download the browser.)

研究信道噪声对M-ary QAM的影响，适合数字通讯从业者(Effect of channel noise on M-ary QAM in)

说明：  单频信号经过多径时变信道后，输出信号的包络随时间随机起伏，输出信号的频谱从冲激谱变成一个窄带频谱。径数位20，变化频率从0—2HZ随机均匀抽取。(Single-frequency signal through time-varying multipath channel, the output signal envelope random fluctuations over time, the output signal from the impulse of the spectrum into a narrow-band spectrum spectrum. Digital Drive 20, changes in frequency from 0-2HZ uniform random samples.)

仿真FH跳频通信系统的整个过程,同时可观察到工作原理及信号等(FH frequency hopping communication system simulation of the whole process can also be observed that the working principle and signal)

C# 串口例子，含有Modbus通讯，已经过测试，保证可用(C# serial port example, contain a Modbus communication, has been tested to ensure that available)

在AWGN信号下，实现pi-4 QPSK调制解调(pi-4 QPSK modulation and demodulation)
