说明：  本代码利用matlab工具，对OFDM系统的调制与解调原理进行仿真。(The code using matlab tools, the OFDM modulation and demodulation system simulation.)

说明：  4. 试说明卷积编解码的工作原理。请用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4 Explain the working principle of convolutional encoding and decoding. Please use the Simulink simulation convolutional coding and Viterbi decoding method used to decode, in which the encoding, decoding all write your own code (S-Function mode), instead of calling the Simulink existing encoding and decoding functions. In additive white Gaussian noise channel, signal to noise ratio and bit error rate to draw the curve.)

harris角点检测的小程序，希望对大家有用，谢谢(harris corner detection of small procedures, we hope to be useful, thank you)

经典的降维方法集合，包含近代诸多算法，由马大博士生编著。(The Matlab Toolbox for Dimensionality Reduction contains Matlab implementations of 32 techniques for dimensionality reduction. A large number of implementations was developed from scratch, whereas other implementations are improved versions of software that was already available on the Web. The implementations in the toolbox are conservative in their use of memory. The toolbox is available for download here.)

we address the design of economical recursive generalized comb filters (GCFs) by proposing an ef- ficient technique to quantize the multipliers in the z-transfer function employing power-of-2 (PO2) terms. GCFs are efficient anti-aliasing decimation filters with improved selectivity and quantization noise rejection performance around the so-called folding bands with respect to classical comb filters. The proposed quantization technique guarantees perfect pole–zero cancelation in the rational z-transfer function of the GCFs, thus totally avoiding instability problems. Moreover, we propose the use of a simple droop compensator for the sake of recovering the passband droop distorting the useful digital signal in the baseband. A design example is proposed with the aim of showing the application of the proposed technique, and a practical architecture of a sample third-order GCF is discussed.

这是一个关于语音信号处理方面的程序，以前做毕业设计的时候在网上收集的，希望对大家有用。(This is a program about the speech signal processing, when done before graduation online collection, we want to be useful.)
