这篇文章详细介绍了CP在OFDM系统中的使用

LTE 是 GSM/UMTS 标准演变和无线数据通讯技术标准。LTE 的目标是使用围绕千年之交开发出的新的数字信号处理技术和调制技术来增加无线数据网络的速度和容量。 进一步的目标是重新设计和简化的网络体系结构，实现基于  请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

PN sequence generation using matlab

雷达直达波和目标回波之间抵消，两个信号一强一弱，既可以抵消强信号，也可以抵消弱信号-Radar direct wave and the target echo offset between the two signals a strong one weak, only to be offset by a strong signal, you can also offset the weak signal

用MATLAB产生GOLD序列，大家可以学习一下~-GOLD sequence generated using MATLAB, we can learn from you ~

这是一篇关于分布式会议的实现的文章,你可以通过sip的扩展功能来实现会议功能,还有P2P协议的参与-This is a conference on Distributed on the realization of the article, you can sip through the extensions to the realization, but also the participation agreement P2P

】　本文主要讨论了Modbus 通信协议的R TU 帧格式中常用的错误校验方法,即循环冗余校验法( CRC) 。 提出了Modbus 协议反转CRC 校验的方法,推导了反转CRC 校验快速计算表格,并用C 语言实现了基于快速查 表算法的循环冗余校验程序。-In this paper, we mainly discuss the Modbus communication protocol R TU frame format commonly used in error checking methods, namely, Cyclic Redundancy Check Code (CRC). Modbus protocol proposed inversion method CRC checksum, CRC checksum is derived fast computing inversion table, and C language to achieve a quick look-up table algorithm based on cyclic redundancy check procedure.
