摘要：
An carrier frequency offset estimation algorithm for IEEE802.11a OFDM frame is presented The proposed algorithm estimates the frequency offset of the OFDM frame in two steps: acquisition and tracking step. It is proved by simulation result that this algorithm has a large estimation range without degrading the variance of the estimation error. Meanwhile, this algorithm has higher throughput efficiency and lower computational complexity than other algorithm using preamble structure for frequency offset estimation.
