APPARATUS AND METHOD FOR CANCELING INTER-MODULATION PRODUCTS

摘要

The present disclosure provides an apparatus (510) and a method (700) for canceling inter-modulation (IM) products in a transceiver. The apparatus (510) includes: a pre-distortion circuit (511 ) configured to estimate a first IM product caused by a transmission signal and pre-distort the transmission signal to cancel the first IM product; an IM product calculator (512) configured to calculate a second IM product caused by the transmission signal in a received signal based on the first IM product; and a subtractor (513) configured to subtract the second IM product from the received signal.
