This simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data. settings.m contains all the common settings to specify all the simulation parameters such as FFT size, number of carriers, input data source file, input and output WAV files, etc. (This simulation script set allows for an OF DM transmission to be simulated.

微弱信号的检测和提取，用MATLAB语言实现，包括了小波法(Weak signal detection and extraction, using MATLAB language, including the wavelet method)

指纹识别系统设计全过程实现 matlab软件环境实现(Fingerprint identification system the entire process of design implementation software environment implementation matlab)

说明：  数字图像处理的matlab版本，里面介绍了各种图像处理的只是(matlab for the digital processing)

第二代曲线波变换工具箱（curvelet）(Second generation wavelet transform toolbox curve (curvelet))

电力系统专业本科生可以看下，用于计算三机九节点系统的潮流(calculation of the power flow)

the attached all programs are based on error control coding for ex. LBC, Convolition, RS code etc. all programs are generalized means for any size input or any type of circuit respectively. the all programs are tested on matlab 2012

说明：  参考文件MAT-FILE打包下载visualC加加MATLAB(MAT-FILE)
