说明：  这是SCMA和polar编码的matlab源文件(This file is the matlab source of the SCMA and polar coded)

语音编码方案的选取对移动通信系统的通话质量、信道容量等有重要影响。本文讨论了TD-SCDMA系统中AMR语音编码的自适应机制，同时分析了AMR中代数码本线性预测(ACELP)算法及实现过程。该方案可以在一块TMS320C5510上实现。(The selection of voice coding schemes for mobile communication systems the quality of the call, such as channel capacity have had a significant impact. In this paper, TD-SCDMA System AMR Adaptive speech coding mechanism, at the same time analysis of AMR in the generation of Digital Linear Prediction (ACELP) algorithm and the realization of the process. The program can be achieved in a TMS320C5510.)

bcjr算法 map形式 适用于卷积码和turbo码(bcjr algorithm map form for convolutional codes and turbo codes)

说明：  ofdm信道估计，采用了LS算法，DFT进行插值(OFDM channel estimation adopts LS algorithm and DFT interpolation)

编写的基于LTE的SC_FDMA程序，其中包括调制、IFFT、子载波映射（分布式和集中式）、FFT及加CP。自己编写，可以运行。(LTE-based SC_FDMA written procedures, including modulation, IFFT, sub-carrier mapping (distributed and centralized), FFT, and plus CP. I have written, you can run.)

本程序是对低密度奇偶校验码的校验矩阵的源程序，相信会对研究ldpc码的人会很有帮助的(This procedure is a low-density parity check matrix of code source, I believe that research on LDPC codes will be very useful)

虚拟串口源码，可用于串口服务器转IP输出，实现不同接口数据的转发( Virtual serial port source code, serial server to IP )

this is a paper for pcf beam splitter!

简单的聊天室，分为服务器和客户端，开发环境为vc6.0，自己答辩用的代码。(Simple chat rooms are divided into servers and clients.)

这是在uwb系统中,用TOA定位法的整个系统的仿真程序(This is the uwb system, using TOA positioning of the whole system simulation program)
