MATLAB

It is BER vs SNR codes for BPSK and 4QAM

Campbell figure is very good method in solving nonlinear dynamics(this code gives a good approximation method to get Campbell figure)

说明：  圖形調整式數位音訊均衡器，使用matlab gui介面寫成。自動畫出頻率響應圖，可讀取.wav檔。濾波器由fdatools設計而成。(Digital audio graphic equalizer adjustments, and the use matlab gui interface language. Automatically draw the frequency response can be read. Wav file. Filter designed with the fdatools.)

汉明码的编解码，成功运行，可看到码型结构，有前后对比(Hamming codecs, run successfully, you can see the pattern structure, before and after)

与simulink联合仿真 用pso算法进行参数优化(Combined with Simulink simulation, PSO algorithm is used to optimize parameters)

说明：  使用MVDR算法进行波束形成并处理宽带信号，该算法分频带进行处理，并最后给出了波束图。(MVDR algorithm is used for beamforming and broadband signal processing. The algorithm divides the frequency band for processing, and finally gives the beam pattern.)

viterbi译码算法，可以对卷积码进行解码。通信类的朋友知道的。。。(viterbi)

对图像进行锐化滤波处理，去除阴影噪声，得到清晰的图像(sharpen filter)

ecg signals for the analysis

本代码在matlab环境下运行，从而出现日历和时间。(Calendar and time display)
