A Carrier Frequency Offset Estimation Algorithm for Arbitary Subcarrier Allocation OFDMA Uplink Systems
任意子载波分配OFDMA上行链路CFO估计及补偿方法

OFDMA is the extension of OFDM. Similar to OFDM, and it is also very sensitive to Carrier Frequency Offset (CFO). In this paper, a pilot-assisted carrier frequency offset estimation algorithm and a low-complexity CFO compensation algorithm are presented. The simulation results illustrate that this algorithm is low-complexity and proposes a high accuracy.
