QPSK modulation with awgn channel

实现语音信号通过低通滤波器后，得到频谱，并且输出滤波前后的图形。(Voice signal through a low pass filter to obtain a frequency spectrum, and outputs the graphic before and after filtering.)

通过FIR滤波器的自适应调整，不断修正其系统函数，使其与未知系统的参数充分逼近，从而使误差最小，达到系统辨识的目的。(Through the adaptive FIR filter, and continuously revise its system function, so that the unknown system parameters with sufficient approximation, so that the smallest error to achieve system identification purposes.)

编写的粒子群(PSO)算法优化Kmeans聚类的MATLAB代码，MATLAB6.5/7.1测试通过，其它版本没测试。((PSO)Kmeans MATLAB6.5/7.1)

this matlab program calculate the return of the DES(cryptage).

Numerical Simulation of Cavity problem with SIMPLE method

MP3 ENCODER USING MATLAB...ENJOY..

The program implements the use of χ2 test for determining the distribution law of fluctuations of the signals. Hypotheses about the distribution of this or innogo parameter system, such as expectation, variance, probability density for a given level of significance accepted or refuted, in accordance with the results. The program implements two distributions: the exponential and Rayleigh.
