This is some MATLAB m-files to simulate a communication system using convlutional channel coding and Viterbi algorith of decoding.

QAM simulator for AWGN, multipath channel

sar成像matlab程序，针对目标电磁特性成像，效果较好(sar image matlab)

this is FDTD with PEC of an infinite linear source within rectangular cylinder

说明：  这是一个创建BP神经网络的matlab源代码，包括BP神经网络的创建、曲线拟合等内容。对初学者很有帮助(This is a create BP neural network matlab source code, including the creation of BP neural network, curve fitting and so on. Very helpful for beginners)

THIS M-FILE USES THE TRANFER MATRIX METHOD TO EVALUATE THE COUPLED-MODE EQUATIONS. THE REFLECTION SPECTRUM OF THE GRATING AND THE TRANSMISSION SPECTRUM, DELAY AND DISPERSION OF THE FABRY-PEROT FILTER ARE SIMULATED

Matlab code for extraction

维纳滤波器，实现宽带窄带干扰滤除，维纳滤波器基础结构，可以给予此机构实现新的算法(Wiener filter, broadband narrowband interference filter, Wiener filter infrastructure, can give organizations achieve new algorithm)

LDPC code construction

The proposed approach satisfies the integrability condition and does not need any boundary condition assumptio-ns, we have designed a stand-alone, flexible Matlab implementation that enables to evaluation the proposed approach. The experiments on real images show the approaches ability to reconstruction the surface from SFS.
