We propose two solutions to combat against the IQ imbalance, multipath fading, phase noise, and additive white Gaussian noise in the IEEE 802.11a environment. We show by computer simulations that our proposed least squared (LS) and least mean squared (LMS) solutions outperform, in terms of bit error rate, the solutions in some other papers. Our LMS solution, which does not require matrix inversion, is more computational efficient than our LS solution. Hence, our LMS solution is of practical use.
