信道编码，很适用,希望对大家的学习有帮助(viterbi_decoder3_zhushi)

This simulation shows the effective SNR verse subcarrier number as a result of band pass filtering of the signal

MATLAB实现快速正交变换，与传统的FFT算法相比拥有更高的分辨率，但是运算时间较大， 在目标检测、频率分析、降噪方面都有着广泛的应用(MATLAB to achieved FOS_convert, compared with the traditional FFT algorithm has a higher resolution, but the computation time is large, the target detection, frequency analysis, noise reduction have a wide range of applications)

这是利用二维小波分析对含高频噪声的图像进行消噪的例程，这里采用的是小波分解系数阈值量化法，(This is the routine use of two-dimensional wavelet analysis denoising images with high-frequency noise, the wavelet coefficients threshold quantization method used here,)

实现匹配滤波的matlab源代码,比较适合初学者！(Achieve matched filter matlab source code, suitable for beginners!)

QAM,PSK,DPSK,FSK,MSK调制仿真，包括眼图输出，误码率输出，星座图，频谱，及实际wav文件的调制解调(QAM, PSK, DPSK, FSK, MSK modulation simulation, including eye diagram output, the output BER, constellation, spectrum, and actual modem wav files)

仿真效果非常好，本科毕设要求参见标准测试模型，脉冲响应的相关分析算法并检验。( Simulation of the effect is very good, Undergraduate complete set requirements refer to the standard test models, Related impulse response analysis algorithm and inspection.)

随机信号分析，包括随机信号的数字特征，相关函数和协方差，带图形显示。(Random signal analysis, including the number of characteristics of random signals, correlation functions and covariance, with graphical display.)

This is a code for 2X2 MIMO system using Alamouti code
