Abstract 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.
