摘要

In this paper, a novel baseband IQ estimation and compensation technique is proposed to overcome the joint effects of CFO and IQ imbalance. The proposed method uses a one-shot algorithm which is able to estimate and compensate the non-ideal effect up to gain error 1 dB, phase error 10 degree, and CFO 50 ppm at carrier frequency 2.5GHz in 64QAM OFDM system. Under this condition, the system performance has less than 0.8 dB design loss in terms of PER and is shown to have more than 10 dB improvement compared with the reference design.
