摘要

在实际的OFDM系统中

符号间干扰(ISI)以及子信道干扰(ICI)仍然是导致系统性能下降的重要因素.本文对循环前缀(CP)长度较短时

产生ISI和ICI机理进行分析和研究

在此基础上提出一种消除ICI的频域均衡的简化方法.经过计算机仿真

结果表明

在宽带无线局域网中采用该算法

误码率明显降低

并且简单实用、易于实现.

Abstract

In the actual OFDM system

the intersymbol interference and interchannel interference can be a dominant factor which degrades the system performance.This paper analyzes how ISI and ICI are produced without inserting CP.Then a simple method of cancelling ICI which can be done in frequency domain based on this theory is proposed.As to the equalization methods discussed in the paper

simulation results are provided which show that in Broadband Wireless LAN bit-error rate (BER) is distinctly reduced and it is applied easily.
