用matlab编写的基于VQ的说话人识别算法（工具箱）(Matlab prepared using the VQ-based speaker recognition algorithm (Toolbox))

自己编写的OFDM发生程序，做仿真的同学可用作源信号，很短，易读，需用matlab工具箱(I have written procedures for OFDM occurred, make simulation the students can be used as a source of signal, very short, easy-to-read, require matlab toolbox)

Photonic crystal is discribed in this matlab code please notice that it does not compatible with any work you want to do,you may modify it to use.

说明：  离散余弦变换的程序，主要对数据的实数部分进行变换(Discrete cosine transform procedure, the main part of the data to transform the real)

说明：  运用粒子群算法进行优化问题分析，程序中以Giewank函数为测试对象，效果不错。(using PSO to conduct optimization, the effect is good based on Giewank function.)

EM-Based Adaptive Frequency Domain Estimation of Doppler Shifts with CRLB Analysis for CDMA Systems

说明：  To find the encryption and decryption of image which is affected by the noise.

gsm tch/fs语音信道传送接收过程仿真，包括外编码卷积码交织过程，仿真得到语音信号的误码率曲线。(gsm/fs voice transmission channel receiver process simulation, including the encoding process convolutional codes are intertwined, Simulation is the voice signal BER curves.)
