Improved Joint Compensation Scheme of Transmitter and Receiver IQ Imbalances in OFDM Systems

摘要：

The in-phase and quadrature-phase (IQ) imbalances can be present at both the transmitter and receiver in OFDM systems and lead to system performance degradation. An improved LS based joint channel and IQ imbalance estimation scheme is proposed. Simulations show that the improved scheme with only two training symbols per frame could achieve better BER performance than the original LS compensation scheme using up to 32 training symbols per frame.
