Abstract:

OFDM has been widely adopted in several communication systems. However, OFDM systems are very sensitive to the phase noise, which causes the CPE (common phase error) and ICI (inter-carrier interference), and thus degrades the system performance signicantly. Based on the IEEE 802.11a standard, a simplied iterative phase noise mitigation algorithm is proposed. The proposed algorithm has very low complexity, and requires no additional pilot information. The simulation result shows that good BER performance can be achieved through several few times of iteration.
