此程序为非二进制LDPC 码的仿真程序. 信道为AWGN, 调制方式 是BPSK.-This program is used to simulation nonbinary LDPC codes over AWGN channel and BPSK modulation. The decoding algorithm is in the probability domain and with the fast Hadamard transform in the check node.

一个用c编的RS编码的程序，采用BERLEKAMP-MASSEY S 算法，输入m,以及信噪比，可得到生成多项式和误码率等。-with a series of RS coding procedures, using BERLEKAMP- MASSEY S algorithm input m, and the signal-to-noise ratio. available generating polynomial and the error rate.

介绍了一种构建在定点DSP上的高速瑞利衰落信道仿真模型。通过应用确知性瑞利过程的理论，使得仅需要较少的低频正弦波分量以及简单的运算即可实现较高精度的信道建模；进而可采用查表法并结合TMS320C6202定点数字信号处理器的高并行性和处理能力构造高速的仿真模型-Construction of a fixed-point DSP in the high-speed Rayleigh fading channel simulation model. Through the application process unascertained Rayleigh theory, only need to make small low-frequency sine wave components and the simple operation can achieve higher accuracy Channel modeling; then use look-up table method and combination TMS320C6202 fixed-point digital signal processor parallel and can handle Construction of the high-speed simulation model

这是完整的垃圾填埋气由乔纳斯 · 库恩在 IMS 写的德语语法。lfg 是短，词法功能语法。此文件可以在 XLE 中运行。 XLE 包括尖端算法用于分析和生成词法功能语法 (LFGs) 和丰富的图形用户界面的编写和调试这种语法。它是为的并行语法项目，为英语、 法语、 德语、 挪威语、 日语和乌尔都语开发工业强度的语法基础。XLE C 编写的并为用户界面使用 Tcl/Tk。它目前在 Solaris Unix、 Linux 和 Mac OS X 上运行。 XLE 的主要目标之一是分析并高效地生成与 LFGs。这是很难的因为 LFG 形式主义，像大多数基于统一的语法形式主义，是 NP 完全性。这意味着最糟糕的情况分析或生成与垃圾填埋气所需的时间可以将输入的长度呈指数增长。然而，自然语言大多是无上下文的相当于和一应能够解析这些大多是立方时间。XLE 旨在自动利用上下文游离度自然语言的语法中，它通常在立方时间分析和生成的线性时间。这允许语法作家写语法中富有表现力的形式主义不一定会牺牲性能的情况下。

PPP Deflate压缩协议（PPP Deflate Protocol） 摘要 点到点协议（PPP）[1]提供了一种在点到点链路上传输多协议数据报的标准方法。压缩控制协议（CCP）[2]提供了一种在PPP封装链路上协商和使用压缩协议的方法。本文档描述了如何使用PPP Deflate压缩协议压缩PPP封装报文。 -PPP Deflate compression protocol (PPP Deflate Protocol) Abstract point-to-point protocol (PPP) [1] provides a point-to-point link, the multi-protocol data transmission of standard methods. Compression Control Protocol (CCP) [2] provides a link in the PPP Packaging consultations on the agreement and the use of compression method. This document describes how to use the PPP Deflate compression compression PPP agreement Packaging paper reported.

OFDMA, Orthogonal Frequency Division Multiple Access is a broad band communication method. Here channel estimation is more crucial. Based on the FFT size used for OFDM transmission method that many number of channel co-efficients are to be estimated and received signals are to be equalized using this co-efficients. Various methods trying to improve the performance and fastness are proposed. As part of master thesis various methods have be studied and evaluated using the WiMAX 802.16 system.
