摘要
在分析子载波间干扰(ICI)产生机理的基础上,提出一种采用联合时频域均衡抑制ICI的算法.理论分析和仿真结果均表明:在一定的条件下,该方法能够有效地抑制ICI的影响,从而使OFDM系统的误码率得到相应的改善.
Doubly-selective fade of channel degrades the performance of orthogonal frequency division muhiplexing(OFDM) system because it introduces the intercarrier interference(ICI). An algorithm of equalization is proposed which combines iteratlve inter-carrier interference mitigation with the 1-tap frequency-domain equalizer, based on an analysis of ICI generation mechanism, Analysis and simulation indicate that the algorithm can suppress the ICI effectively and improve the performance of bit-error rates of OFDM system.
