附件包含离散信道以及各种信道编码的matlab仿真(Annex contains the discrete channels and a variety of channel coding matlab simulation)

这是我师兄做的空间谱估计的内容。这只是一小部分程序，希望大家能够接受，下载吧。(this done I saw the space Spectral Estimation content. This is only a small part of the procedure, hoping that everyone can accept, download it.)

使用LPCC参数来生成源滤波器模型的的线性预测系数(LPCC parameters to generate the linear prediction coefficients of the source filter model)

This is the code of l1-norm for Lotka-volterr Model

2维曲面拟合，gauss or gabor 函数(Functions to fit a 2D Gaussian or 2D Gabor to a surface. The routines are automatic in the sense that they do not require the specification of starting guesses for the model parameters. This is done by evaluating the quality of fit (sum of squared error) for many different choices of parameters then refining the most promising set of params through least-squares (exhaustive search followed by refinement). Least-squares is statistically equivalent to maximum likelihood estimation of the model parameters on the assumption of independent, normally distributed Gaussian noise in the observations (pixels). autoGaussianSurf(xi,yi,zi) fits a Gaussian,)

一个利用matlabGUI设计的学生成绩查询的小系统，还需要进一步完善。( Type text or a website address or translate a document. Cancel Yīgè lìyòng matlabGUI shèjì de xuéshēng chéngjī cháxún de xiǎo xìtǒng, hái xūyào jìnyībù wánshàn. Example usage of "": automatically translated by GoogleChinese (Simplified)EnglishSpanish AlphaA using matlabGUI design student achievement query system, still need further improvement.)

Aim: do walsh coding with hamming distance.To compare WALSH decoding for synchronous CDMA with decoding using hamming distance. a) System should be supplied with correct/ corrupted version (one/ two bit) of transmitted walsh code(s) b) System should also have table for correct codes(walsh codes) c) System should ab able to deocde the same using hamming distance property. d) Copmare resutls for corrupted code(s) to check the efficacy of WALSH decoding technique (as in above experiment) compared to hamming distance decoding.

说明：  蚁群算法简单快速入门，有利于初学者快速了解蚁群算法的过程。(The ant colony algorithm is simple and quick.)

Transforming images from the spatial domain to frequency domain using FFT and DCT, also it includes transforming to the Cepstrum domain.
