RF METHOD OF REMOVING SELF-INTERFERENCE SIGNAL USING RF BAND SIGNAL AND BASEBAND SIGNAL AND APPARATUS USING THE SAME

摘要

Disclosed are a method for removing a self-interference signal and an apparatus therefor. A self-interference signal cancellation method according to an embodiment of the present invention includes estimating a first channel value using an RF band signal; estimating a second channel value using a baseband signal; generating a first self-interference signal using the first channel value; generating a second self-interference signal using the second channel value; generating a cancellation signal by weighted summing the first self-interference signal and the second self-interference signal; and performing self-interference signal cancellation using the cancellation signal.
