matlab code of dgital communication

常用的MATLAB图像压缩编码，通过matlab实现，其中包含了DM编码、变换编码（FFT和DCT）、算术编码、行程编码、JZOTch编码、线性预测编码和一个近似的NHzjZsp编码过程。本人通过MATLAB编码效率很高。 (Commonly used MATLAB image compression coding, through matlab implementation, which includes the DM coding, transform coding (FFT and DCT), arithmetic coding, run length coding, JZOTch coding, linear predictive coding and an approximate NHzjZsp encoding process. I have a high coding efficiency by MATLAB. )

用matlab模拟全电视信号，包括场、行消隐脉冲，亮度信号，色度信号，色同步信号(Matlab simulation with the whole television signal, including the field, line blanking pulse, luminance signal, chrominance signal and color sync signal)

matlab file for photonic crystal

用于文本语义分析的潜在语义分析算法LSA(Latent Semantic Analysis)，包含详细的函数说明，原理分析及数据。相比原来版本的LSA，增加了文件demo.m以增加可视化效果，更有利于读者使用。(-Semantic Analysis for Text of Latent Semantic Analysis Algorithm LSA (Latent Semantic Analysis), contains a detailed description, principles of function analysis and data. Run demo.m can see the visualization effect.)

matlab计算一种图形颗粒识别参数，该参数是通过小波分解的能量参数来定义的(matlab computing a graphical particle identification parameter, which is defined by the parameters of wavelet decomposition energy)

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.)

QAM constellation with noise and channel(QAM constellation)

用MATLAB编写的svm源程序，可以实现支持向量机，用于特征分类或提取(MATLAB svm prepared by the source, can achieve a support vector machine for the feature classification or extract)

The ADPCM package is a flexible simulation tool for an adaptive differential encoder and decoder with backward predictor adaptation. It uses an LP-based (Burg) adaptive predictor and a nonuniform quantizer with mu transfer function. It generates the encoded bitstream and estimates the efficiency of a Huffman code for the compressed sequence.
