... paper, we have proposed training-based compensa- tion schemes for OFDM systems impaired with transmitter and receiver IQ imbalance. The proposed schemes can decouple the compensation of the transmitter ... The proposed schemes result in an overall lower training over- head and a lower computational requirement. Simulation results show that the proposed schemes provide a very efficient...
