一篇关于802.16信道的文章，几个通信大牛的力作，里面还包括对于SUI信道的matlab基本仿真程序。相信对于搞无线的人，这篇文章的价值不言而喻！(a 802.16 Channel on the article, several large cattle communication ability, which also includes SUI channel for the basic Matlab simulation program. Believe engage in the wireless, the value of this article is self-evident!)

MATLAB是大家常用的开发工具，尤其是在研究生阶段和读博士期间，这是一个关于人工神经网络的matlab程序，可以运行的哦(MATLAB is commonly used development tools, especially at the graduate level and duration of the PhD, which is an artificial neural network on matlab program, you can run, oh)

： 正交频分复用( O F D M) 是第四代移动通信的核心技术。 该文首先简要介绍了O F D M基本原理， 重点研究了理想同步情 况下， 保护时隙( c P )和不同的信道估计方法在高斯信道和多径瑞利衰落信道下对O F D M系统性能的影响。 在给出O F DM系 统模型的基础上， 用 MAT L A B语言实现了整个系统的计算机仿真并给出参考设计程序。 最后给出在不同的信道条件下， 保 护时隙、 信道估计方法对 OF DM系统误码率影响的比较曲线， 得出了较理想的结论。 关键词： 正交频分复用； 仿真； 循环前缀； 信道估计(good)

去斜处理（宽带的匹配滤波）Stretch方法是针对线性调频信号而提出的， 其方法是将输入信号与参考信号 （经适当延迟的本振信号， 延迟量通常由窄带信号测距结果估计出） 混频 ，则每一个散射点就对应一个混频后的单频分量，对混频输出的信号进行 DFT 处理 ，即可获得目标的距离像，对参考信号的要求是应具有与输入信号相同的调频斜率。(dechirp matched filter Stretch method is proposed for linear frequency modulation signal. It mixes the input signal with the reference signal (local oscillator signal with appropriate delay, the delay is usually estimated from the result of narrowband signal ranging). Then each scattering point corresponds to a single frequency component after mixing, and DFT is performed on the mixed-frequency output signal. The range profile of the target can be obtained by processing, and the reference signal is required to have the same frequency modulation slope as the input signal.)
