基于傅里叶变换的数字水印算法，实现了图像里的水印的嵌入和提取。Matlab代码。(Fourier transform-based digital watermarking algorithm to achieve the image in the watermark embedding and extraction. Matlab code.)

用改进的星座图扩展法降低OFDM信号峰均功率比(Improved constellation expansion method to reduce the OFDM signal peak to average power ratio)

OFDM的性能仿真，绝对的好资料，在LTE和OFMDA中都有运用。(OFDM-performance simulation, the absolute good information, both in LTE and OFMDA in use.)

说明：  搭建汽车操纵稳定性和平顺性仿真中常用的魔术轮胎和dugoff轮胎，整理到一个simulink文件中，两种轮胎的模型均已和carsim中的仿真结果进行对比和验证，精度较高。(The magic tire and Dugoff tire commonly used in vehicle handling stability and ride comfort simulation are built and sorted into a Simulink file. The two tire models have been compared and validated with the simulation results in Carsim, and the accuracy is high.)

this is a sample code for rat slam in matlab code.

解模块线性方程组, solve modular linear equations, 用到了extended-euclid算法求最大公约数...(solve modular linear equations, use extended-euclid to compute the greatest common divisor..)

这是Victor C.Chen"The Micro-Doppler Effect in Radar With DVD"的书还有它的Matlab的程序。(This is Victor C.Chen s book "The Micro-Doppler Effect in Radar With DVD" with Matlab codes.You have to put the codes on the Matlab folder that you can excute it.)
