Multi variable control tool

说明：  通信系统中一种常见的数字调制方法，16—QAM调制(QAM)

prise en main matlab

基于铌酸锂MZ调制器，通过展开，计算其三阶互调失真以及SFDR等(Based on lithium niobate MZ modulator, by expanding to calculate the third-order intermodulation distortion and SFDR etc.)

介绍UBM模型MAP算法过程，对于说话人识别有帮助(UBM model describes the process of MAP algorithm for speaker recognition helpful)

这是用MATLAB实现的有限数字滤波器设计，与发的滤波器设计一起学，效果会更好(This is achieved using MATLAB limited digital filter design, the filter design and development with science, the effect will be even better)

Gaussian Mixture Utilities

设计一个离散hopfield网络，实现联想记忆，以对模糊数字进行识别，判断。(design of a discrete hopfield network, associative memory, a pair of fuzzy figures for the recognition, judgment.)

simulate two channel tdm using matlab

BER verses SNR in ofdm with amplifier: The BER performances of OFDM systems over the AWGN channel are given by the BER where N=512. We see that SNR required for BER=10-3 No channel coding scheme is adopted. Therefore, BER is a bit higher. The results with 16 QAM show that the required Signal to Noise Ratio (SNR) for BER=10-2 is almost the same. This is because the noise is the dominant.
