In future high-speed communication networks, the in-phase/quadrature (I/Q) imbalance mitigation and oscillator drift compensation is a key issue in the design of orthogonal frequency division multiplexing (OFDM)-based wireless LAN (WLAN) transmitters. To this end, we propose a two-stage I/Q imbalanc...
