Abstract
The present invention discloses a Zero-IF receiver in a Time division Duplex TDD system, a correction method therefor and a base station associated therewith. The Zero-IF receiver comprises a Radio Frequency RF circuit, a baseband circuit, and a correction circuit for correcting baseband signals from the baseband circuit based on correction parameters. Said Zero-IF receiver further comprises a training signal providing part for providing a training signal to train the correction circuit to adapt said correction parameters, and a training signal coupling part for coupling said training signal to the baseband circuit during an idle period of the Zero-IF receiver to enable the correction circuit to adapt said correction parameters based on said training signal. The present invention provides stable and reliable training signals that can be used to adapt correction parameters of a correction circuit to improve receiver performance.
