Cooperation_diversity_through_coding

this is a project for voice recognition in matlab using vector quantization.

针对信号分选的几种常见算法，包括pri变换，sdif（序列差直方图）算法，cdif（累积差直方图）算法，可以解决类似于固定重频信号，抖动重频信号，滑变重频信号和参差重频信号的分选等(For several common signal sorting algorithms, including pri transform, sdif (sequence difference histogram) algorithm, cdif (cumulative difference histogram) algorithm, can solve similar fixed repetition frequency signals, jitter signal repetition, repetition becomes slippery sorting and mixed signal repetition frequency signals, etc.)

通过代码计算根升余弦滤波器系数，并通过与matlab本身自带生成函数做了比较(By code calculates root raised cosine filter coefficients, and through matlab comes with its own generating functions were compared)

循环谱估计，能画出２维图，也能在某特定循环频率下画出１维图(Cyclic spectrum estimation, can draw 2 d figure, also can draw slices under a cyclic frequency)

基于MATLAB的时频分析方法之一，Wigner Ville Distribution(Wigner Ville Distribution)

说明：  杂波的一个MATLAB仿真，杂波的产生：先生成一个（0，1）分布的随机数r，让后根据poission分布产生杂波的个数n，这n个杂波是服从均匀分布(Clutter a MATLAB simulation, the resulting clutter: a President (0,1) distribution of the random number r, let poission distributed according to the number of clutter have n, that n is subject to a uniformly distributed clutter)

高斯白噪声信道下接收端对发送信号的恢复效果(Gaussian white noise channel receiver, the recovery of the transmitted signal)

MATLAB编写的3个简易计算器程序，hh那个是本人综合另两个写出来的，简易好用。具体用法不用我说了，大家将所有代码放在MATLAB安装文件的work里面即可。可能还需要GUI绘图，具体我忘了，一年前做的。(MATLAB prepared by the three simple calculator program, which is my hh another two comprehensive written, Simple handy. I do not have specific directions said, we will put all of the code of MATLAB installation work will be inside. May also need GUI drawings, specific, I forgot, a year ago to do.)

数字信号处理理论、算法与实现的相关MATLAB程序,是清华经典教程的配套程序.(digital signal processing theory, algorithms and implementation of procedures related to MATLAB, Tsinghua is the classic guide to the matching procedures.)
