是学习matlab的很好程序资料 可以用来方便设计iir滤波器(Matlab is a good learning process can be used to facilitate the design of filter iir)

说明：  使用matlab进行图象处理的经典命令.(picture command)

Simple program that encrypts and Decrypts text with options to generate/Open and Save key.

简化的OFDM系统仿真，其中暂未考虑扰码和卷积码，物理层参数采用802.11a参数，1个长训练符号与6个OFDM数据符号构成1帧，信道为单径rayleigh衰落信道，其中最大多普勒频移为100Hz，信噪比0-30dB，调制方式为QPSK和16-QAM。(Simplified OFDM system simulation, which yet consider scrambling and convolution codes, physical layer parameters using 802.11a parameters, a long training symbols and six OFDM data symbols constitute a channel for single-path rayleigh fading channel, one of the largest Doppler shift is 100Hz, the SNR 0-30dB, the modulation scheme is QPSK and 16-QAM.)

OFDM 对频偏非常敏感，文件主要是基于导频方法的频偏估计(OFDM is very sensitive to frequency offset, frequency offset file is mainly based on the pilot estimates)

说明：  基于小波变换的阈值去噪，对含噪声图像进行阈值去噪(Threshold based on wavelet transform denoising of images with noise threshold denoising)
