Abstract: |
In the presented paper a new method of estimating and correcting transmitter-caused I/Q imbalance in a transmission system based on the WLAN standard IEEE802.11a is proposed. The estimation process consists of an initial estimation followed by an iterative tracking of the I/Q imbalance parameters. Additionally, with the modified preamble structure presented in this paper a further improvement in estimation quality can be achieved. At the receiver the I/Q imbalance correction based on the estimated parameters leads to a significant performance gain as we will show in our simulation results.
