说明：  MATLAB 工具包 很不错的东西 (MATLAB tool kit is a good thing)

Chaotique algorithm Image

这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解调解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 (This is a space-time block coding based simulation design MIMO_OFDM communication systems. This system includes a QPSK modulation and demodulation demodulation, IFFT modulation, space-time coding and decoding, channel estimation based training symbol communication module.)

Script to solve the heat equation in soil with seasonal temperature forcing

这是关于用MATLAB实现遗传算法程序的原理介绍，包括也选择、交叉、变异等算子的程序。(This is about using MATLAB genetic algorithm program to achieve the principle of description, including also selection, crossover and mutation operators of the program.)

Neural fuzzy approximator construction basics

This Simulink model simulate GMSK modulatino in Rayleigh channel.

Watermarking, as opposed to steganography, has an additional requirement of robustness against possible attacks. An ideal steganographic system would embed a large amount of information perfectly securely, with no visible degradation to the cover object.

模拟调制解调：AM、DSB、LSB及FM。（通过AWGN噪声信道）(Analog modulation：AM、DSB、LSB and FM。)
