1. 基于simulink搭建一个QPSK发送链路，QPSK调制信号经过了瑞利衰落信道，观察信号经过衰落前后的星座图，观察信道特性。仿真参数：信源比特速率为500kbps，多径相对时延为[0 4e-06 8e-06 1.2e-05]秒，相对平均功率为[0 -3 -6 -9]dB，最大多普勒频移为200Hz。(1. Based on simulink structures, QPSK sent a link, the Rayleigh fading channel after the QPSK modulation signal, were observed before and after signal after the decline of constellation diagram, observation channel characteristic. Simulation parameters: the source is 500 KBPS bit rate, relative multipath time delay of [0 8 e 4 e- 06-06 e-05] 1.2 seconds, the relative average power is [0-3-6-9] dB, most of the doppler frequency shift is 200 hz.)

iforest算法可以进行对时间序列中异常的一段时间进行检测，算法非常高效(Iforest algorithm can detect abnormal periods in time series, and the algorithm is very efficient.)

说明：  基于matlab 的 iir高通滤波器设计，可以过滤150Hz以下的噪声；使用时把音频路径替换正自己的音频路径即可运行。(The design of IIR high pass filter based on Matlab can filter the noise below 150Hz; when using, the audio path in the file can be changed to its own path to run)

2ask的调制解调，包括相干解调和非相干解调，并有两者的性能分析(2ask modem, including coherent demodulation and non-coherent demodulation, and performance analysis of both)

做遗传算法研究的必备工具箱，非常好用。希望对大家有所帮助，共同学习进步！(Must do genetic algorithm toolbox, very easy to use. Help, we hope to learn together and progress!)

根据采样定理对信号采样，之后依据采样值恢复原信号。恢复的信号基本一致，验证性(Signal is sampled according to the sampling theorem, and then restore the original signal based on sampled values. Recovered signal basically the same, confirmatory)

基于MATLAB的遗传算法程序，所用的函数为测试函数(Genetic algorithm based on MATLAB program, the use of function test function)
