MIMO-OFDM channel estimation 。是基于mmse准则的，欢迎大家下载使用。(MIMO-OFDM channel estimation. Is based on the MMSE criteria, welcomed everyone download.)

在Matlab中实现了Cordic快速算法，并实现了sin(x), cos(x), atan(y/x), sqrt(x^2+y^2)等函数的快速计算，并附加了误差分析的结果图，代码清晰简洁，对Cordic算法的迭代次数确定，有一定的指导意义(Cordic implemented in Matlab fast algorithm, and realized sin (x), quickly calculate cos (x), atan (y/x), sqrt (x ^ 2+y ^ 2) and other functions, and attach the results of the error analysis Figure, clear concise code, Cordic algorithm for determining the number of iterations, there are certain guiding significance)

毕设题目，我用MATLAB程序编写的实现基于矢量量化的说话人识别系统，结合了TNIErq算法。在给定的temp.wav录音文件的情况下，对不同的人的不同时间长度的语音进行辨识。实现与文本无关的自动说话人确认的实时识别。 使用步骤包括： 1 训练，2 KWMnxOx， 3 测试 4， 输出结果。 (Complete set topic, I use a program written in MATLAB-based VQ speaker recognition system, combining TNIErq algorithms. In the case of a given temp.wav audio file, voice different people different lengths of time were identified. Real-time recognition and text-independent speaker verification automatically. Use steps include: 1 training, 2 KWMnxOx , 3 test 4, the output result. )

流水线模数转换电路输出信号做fft后求SNR,SNDR的matlab程序(matlab fft program for SNR and SNDR of pipelined analog to digital converter（ADC）)

这是本人在学习过程中总结的matlabbode图的绘制技巧，希望对大家有用(This is summarized in the learning process, I the matlabbode map drawing skills, and hope to be useful)

The function impulsive_noise generates non-gaussian noise with inputs of beta, gamma,and the power of noise is 1 in W or 0 in dB. The noise can be defined either real or complex. The other functions generate QAM symbol and insert a vector to another vetor with specific locations

说明：  课程设计上用matlab编写的16qam的译码，很好用的.m文件。(Curriculum design 16qam written with matlab decoding, the good. M file. )
