| Abstract: | In this paper, we study the joint estimation and compensation of frequency selective in-phase and quadraturephase (I/Q) imbalance and carrier frequency offset (CFO) for OFDM systems. We propose an iterative method to solve the joint estimation problem using training sequences. Unlike most earlier methods, we need only one arbitrary OFDM block for training. Simulation results show that the iterative algorithm converges very quickly and the proposed method has a good performance. The BER performance is only slightly worse than the ideal case where the I/Q mismatch, CFO and channel response are perfectly known at the receiver. |
