IQ IMBALANCE COMPENSATION IN INTERFERENCE CANCELLATION REPEATER USING A ZERO-IF RADIO ARCHITECTURE
摘要
<p>An interference cancellation repeater employing zero-IF or direct conversion radio architecture implements IQ imbalance compensation using a metric and an adaptive algorithm. The metric is based on the image rejection ratio of the repeater and is indicative of the level of spectral image caused by the repeater's receiver or transmitter IQ imbalance.</p>
