通信网络 OFDM系统中降低峰均功率比的研究
正交频分复用技术（Orthogonal Frequency Division Multiplexing， OFDM）非常适合高速通信系统，但存在高峰均功率比（PAPR）的问题。对OFDM系统中如何降低PARR的问题进行了研究，讨论了降低PAPR的主要方法，重点分析了选择性映射法（SLM），并在此基础上提出了一种基于预编码矩阵的改进算法，最后通过matlab进行了算法仿真 ...
无线通信 克服了正交频分复用(OFDM)和IEEE 1901.2智能电网通信的挑战
Abstract: While many questions still surround the creation and deployment of the smart grid, the need for a reliablecommunications infrastructure is indisputable. Developers of the IEEE 1901.2 standard identified difficult channel conditionscharacteristic of low-frequency powerline communications ...
无线通信 降低OFDM信号PAPR的方法研究
正交频分复用 （Orthogonal Frequency Division Multiplexing，OFDM）是一种多载波调制技术，由于具有良好的抗多径干扰性能，适用于高速数据传输，OFDM成为近年来人们研究的热点。但是其峰均比较高，应用受到了限制，因此有必要研究降低PAPR的方法。本文首先介绍了OFDM的基本原理和PAPR的基本概念，然后讨论了目前常用的 ...

学术论文 OFDM仿真及实现
OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。每个子信 ...
