precoding

minimum spacing between 2 carrier to be orthogonal

training vector quantization LGB

一个用matlab做的电话声学回声消除程序(Using matlab to do a telephone acoustic echo cancellation procedures)

实现BP网络算法，并对数据进行分类实验。matlab编写。(Achieve BP network algorithm, and data classification accuracy. matlab preparation.)

说明：  用matlab对多天线技术（MIMO）进行仿真，其中检测用KBEST算法。对信道H进行MMSEQSORT分解。后接BCJR解码器(Using matlab language to simulate the multi-input multi-output system. KBEST algorithm is used for detection, then followed by BCJR decoder)

说明：  lorenz系统分岔轨迹绘制，包含吸引子图，X,Y,Z相时间序列(lorenz draw bifurcation path, including the attractor graph, X, Y, Z-phase time-series)

Image treatment file:image filters and beginners commands

scilab,开源数值计算方针软件。实现不同信噪比条件下的频域变换仿真程序，可完美兼容matlab。(Scilab, open source software for numerical calculation principle. Than the frequency domain transform simulation program under different signal-to-noise to achieve, can be perfectly compatible with matlab.)

this is improved prony method that is very strengs for noisy signal

this code is very helpfulful in understanding the basic sterps to create klt algorithm
