In this work, a grouped linear constellation precoded orthogonal frequency-division multiplexing (GLCP OFDM) system, with the transceiver in-phase/quadrature (I/Q) imbalance operating over frequency-selective fading channels are studied. A new subcarrier grouping scheme in such a system is proposed. Through analysis and simulations, we demonstrate that with the proposed scheme, low-complexity solutions can be developed to mitigate I/Q imbalance, and provide a performance comparable to (or better than) the optimal subcarrier grouping scheme with no I/Q imbalance. copy; 2009 IEEE.
