: 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。

it is a project of socket programming in linux . it was witten in c language .
it has two parts client and server .
clients can connect to server and use some services from server and server service client.
client can be more than one but server just one.
