《Experiments with MATLAB》这本书的程序源码，附中文注释，简单易懂，是学习MATLAB编程语言的极好方式。(" Experiments with MATLAB" This book is Open Source, with Chinese notes, easy to understand, is an excellent way to learn MATLAB programming language.)

用Matlab仿真OFDM系统时所需的载波映射及逆映射程序(Matlab simulation with the desired carrier OFDM system mapping and inverse mapping program)

利用周期图法对序列的功率谱进行估计。数据窗采用汉明窗。假设在白噪声中分辨这三个不同频率的正弦信号,其相位是均匀分布在2PI的独立随机变量,而 是一个单位白噪声.生成50个长度为N=512的 的样本序列集合。 (use map cycle sequencing method of the power spectrum estimation. Data window using Hamming window. Assume that the white noise to differentiate between the three different frequency sinusoidal signal, its phase is uniformly distributed in the PI two independent random variables. but a flat white noise. Generating 50 length N = 512 samples of the sequence set.)

MATLAB CODE FOR DELTA MODULATION TECHNIQUE FOR ANY SIGNALS

将带发送数据序列映射为格雷码，相邻的码元只有一个符号不同。(mapping the deta serial into GeLei code,whose closed code only one symbol is different)

Matlab Turbo coding

首先由计算机产生[1,100]之间的随机整数，然后由用户猜测所产生的随机数。根据用户猜测的情况给出不同提示，如猜测的数大于产生的数，则显示“High”，小于则显示“Low”，等于则显示“You won”，同时退出游戏。用户最多可以猜7次。(First produced by the computer [1100] between a random integer, then by the user to guess generated random numbers. According to the user guesses are different tips, such as guess the number is greater than the number, then displays " High"," Low", smaller than the display to show " You won", at the same time to quit the game. The user can have up to7 guess.)

粒子滤波入门外文经典文献，非常值得一看，有助于理解基本粒子滤波算法。(Particle filter entry of foreign classic literature, well worth a look, help to understand the elementary filtering algorithm.)
