Abstract
In this paper, we present a baseband algorithm for estimation and compensation of transmitter and receiver IQ imbalance for OFDM in a frequency-selective fading channel. We show by simulations that the negative effect of IQ imbalance on system performance can be almost completely removed by the proposed algorithm. The algorithm is an iterative loop, consisting of consecutively channel estimation, Rx IQ imbalance estimation, Tx IQ imbalance estimation and data estimation
