Abstract

An efficient IQ imbalance estimation and compensation scheme for MIMO-OFDM systems is proposed. The scheme exploits the inherent data structure imposed by Space Frequency Block Code (SFBC), for lowering the implementation complexity. As such, no further requirements are laid on the preamble design. The proposed algorithm can be easily extended to the MIMO-OFDM systems using STBC or with frequency-selective IQ imbalance. Simulation results demonstrate the accuracy and effectiveness of the proposed IQ imbalance estimation scheme in practical MIMO-OFDM scenarios such as LTE.
