利用MATLAB实现了二元光学设计中的GS算法以及达曼光栅的设计。GS算法是用于光束整形的重要算法，达曼光栅是常见的均匀分束二元光学器件。(Implemented using MATLAB binary optical design of the GS algorithm and Dammann grating design. GS algorithm is an important algorithm for beam shaping, Dammann grating is a common uniform beam of binary optics.)

目前学习DTC的最新成果，希望可以互相借鉴，有什么不足，望指教！(DTC is currently studying the latest achievements, hoping to learn from each other, what inadequate, Wang Zhi Jiao!)

This is also related to shift keying mod technique.....it is also very helpfull for the biggner who want to do digital mod techniques.........

直接运行MAIN文件。对音频文件滤波，完成低通和高通滤波，并保存为WAV文件。(Run directly MAIN file. Filtering of the audio file to complete the low-pass and high-pass filter, and save it as WAV files.)

In this work, the Mel frequency Cepstrum Coefficient (MFCC) feature has been used for designing a text dependent speaker identification system. The extracted speech features (MFCC’s) of a speaker are quantized to a number of centroids using vector quantization algorithm. These centroids constitute the codebook of that speaker. MFCC’s are calculated in training phase and again in testing phase. Speakers uttered same words once in a training session and once in a testing session later. The Euclidean distance between the MFCC’s of each speaker in training phase to the centroids of individual speaker in testing phase is measured and the speaker is identified according to the minimum Euclidean distance. The code is developed in the MATLAB environment and performs the identification satisfactorily.
