| 摘 要： | OFDM系统对载波频率偏移(CFO,CarrierFrequencyOffset)非常敏感,由此产生的ICI将严重影响系统的接收性能。分析了载波偏移对系统ICI的影响,提出了一种可用于OFDM无线局域网系统的载波频率偏移估计算法,同时对估计和补偿算法的实现结构作了详细的说明。

| Abstract: | OFDM system is highly sensitive to Ca rrier Frequency Offset(CFO).The CFO leads ICI in OFDM system.that will damage the performance of r eceiver.We present a CFO estimation and compensation algorithm for the OFDM-based wireless local area networks(WLANs )with low complexity.The realizable structure of the algorithm is also described. |
