Abstract
Embodiments of the present invention relate to the field of communications technologies, and provide an interference cancellation apparatus and method, which can avoid being limited by a dynamic range of an ADC/DAC and can cancel a second-type self-interference component effectively. The interference cancellation apparatus includes a main receive antenna, a divider, a first-type interference canceller, a down converter, a filter, a coupler, a digital down-conversion unit, a second-type interference reconstructor, and a local-frequency signal generator. The present invention is used for interference cancellation.
