用于循环前缀ofdm同步，算法很简单，熟悉此算法原理的人更容易看懂。(Cyclic Prefix for OFDM synchronization algorithm is very simple, familiar with the principles of this algorithm easier to understand.)

This Simulink model simulates as an example the transmission and reception of random digital data modulated with GMSK. The purpose of this model is to illustrate how part of the GSM transmission and reception works. It also measures the BER, affected by an AWGN channel.

说明：  Matlab数据挖掘分析与实战教程，包括matlab基础知识与机器学习算法，实战部分包含10大具体实例及讲解(Tutorial of Matlab data mining analysis)

This is also related to shift keying mod technique.....it is also very helpfull for the biggner who want to do digital mod techniques.........

LDPC decoder for Chinese DTV standard. This code works for all code rate,only need to change is Paritycheck matrix.I have tried with 1/2 code rate.

说明：  用matlab软件计算电力系统的潮流，使电力系统运行可靠(Power systems using matlab software to calculate the trend, so that the power system is reliable, )

是基于傅里叶变换的数字图像水印的matlab源代码(Is based on the Fourier transform of digital image watermarking matlab source code)

matlab code for inter and intra row permutation also showing the effect of asymmetric turbo code performance.

Particle swarm optimization

This Matlab script finds the frequency offset effects in the orthogonal frequency division multiplexing (OFDM)and its effects on the bit error rate (BER). A reference paper is also included.
