Title:
METHOD FOR REMOVING SELF-INTERFERENCE SIGNAL IN FDR ENVIRONMENT AND COMMUNICATION APPARATUS FOR SAME
Document Type and Number:
WIPO Patent Application WO/2017/159930
Kind Code:
A1
Abstract:
A communication apparatus for eliminating a self-interference signal in an FDR environment comprises: a distributor for distributing signals from a transmission chain to a plurality of lines in a receiving chain; a first self-interference signal replicating unit for generating a self-interference replica signal of a signal distributed to a first line from among the plurality of lines by the distributor; a second self-interference signal replicating unit for generating a self-interference replica signal of a signal distributed to a second line from among the plurality of lines by the distributor; and a self-interference eliminating unit for eliminating self-interference by deducing, from the signals distributed by the distributor, a signal generated by the first self-interference signal replicating unit and a signal generated by the second self-interference signal replicating unit.
