Title:
METHOD FOR PERFORMING SELF-INTERFERENCE CANCELLATION BY COMMUNICATION DEVICE USING FDR MODE
Document Type and Number:
WIPO Patent Application WO/2016/195204
Kind Code:
A1
Abstract:
A method for performing self-interference cancellation by a communication device which uses an FDR mode can comprise the steps of: measuring the strength of a residual self-interference signal, after antenna and analog self-interference cancellation, for each subband with respect to a predetermined number of subbands configured in a communication device; determining the order of a nonlinear self-interference signal component, to be considered for channel estimation of a nonlinear self-interference signal, for each subband on the basis of the strength of the residual self-interference signal that has been measured for each subband; and performing channel estimation of the nonlinear self-interference signal on the basis of the order that has been determined for each subband.
