Alamoutti space time code

the fuzzy c means program !!

matlab时间序列预测，本程序采用遗忘因子算法的方式实现(Matlab time series prediction that the adoption of the forgotten factor algorithm in a way)

语音增强的多带谱减算法,函数可直接调用，简单易操作(Speech enhancement of the multi band spectral subtraction algorithm, the function can be called directly)

OFDM信号在无线通信中会受到多普勒频移的影响，从而影响了OFDM信号的正交性，引起载波间的干扰和OFDM信号符号间的干扰，本代码先形成含有N个二进制码元的信号，而这个信号的前半部分和后半部分的信号是一样的，然后根据把这个信号调制成OFDM信号，最后接收端根据这个OFDM信号估计出多普勒因子(OFDM signal in a wireless communication will be subject to Doppler shift of influence, thus affecting the OFDM signal orthogonality, causing interference and interference between the OFDM signal symbol between carriers, the code first formed comprising N binary symbols signal, and the first and second halves of this signal is the same signal, and then the OFDM signal according to the estimated Doppler factor modulates the signal to the OFDM signal received, the last side)

说明：  应用matlab完成邻域平均法来实现数字图像去噪(Digital image neighborhood average method denoising realization )

说明：  本文章阐述了如何产生m序列，对初学者是一份很重要的资料(This article describes how to generate m sequence, for beginners is a very important information)

ADP算法最原始的代码，适用于2012年自适应动态规划论文(2012 JZP paper Adaptive Dynamic Programing by Counting linear system)

this function block an Arbitrary image and take dct from each block. for check quality of reconstructed image calculated PSNR.

LTE系统中误块率BLER的求解计算，BLER是个衡量系统好坏的正确指标(LTE system for solving block error rate BLER calculation, BLER measurement system is good or bad right index)
