时变信道的频率选择性和时变性。系统的输入是一个BPSK信号。系统的时变特性使BPSK信号作为时间的函数，发生衰减和相位旋转。(Time-varying channel frequency selectivity and time variability. Input to the system is a BPSK signal. System is time-varying characteristics make BPSK signal as a function of time, the occurrence of attenuation and phase rotation.)

MATLAB环境下，CRC-8生成校验码(MATLAB environment，CRC-8，Parity bit)

说明：  可以将信号很好的进行LMD分解，很好用，自己试试看(The signal can be well decomposed into LMD)

Matlab讲义高级第4章，大家分享一下(Matlab senior notes, Chapter 4, we share)

利用zhang suen快速并行的算法 实现了字符图像的细化功能 有较好的细化效果(Use of the the zhang suen fast parallel algorithm to achieve the refinement of character images function better refinement effect)

说明：  主要是介绍卡尔曼滤波器的原理，并形象地说明了实现过程，最后用matlab实现了这一原理。(Mainly to introduce the principle of Kalman filter, and vividly illustrates the realization of the process, and finally use matlab to achieve this principle.)

基于802.1a 标准下ofdm的整套仿真(the entrie simulate ofdm system program base on the 802.11a standar )

design drive induction motor

各种优化方法程序，内点法、外点法、乘子法等(Various optimization program, interior point method, outside the point method, multiplier method)

MATLAB中常用的程序，包括硬阀值、软阀值、全局阀值，小包波去噪等等，希望对初学者有用。(Procedures commonly used in MATLAB, including the hard threshold and soft threshold, global threshold, wave packet de-noising, etc., in the hope that useful for beginners.)
