Title:
APPARATUS REMOVING SELF-INTERFERENCE IN ENVIRONMENT SUPPORTING FDR METHOD
Document Type and Number:
WIPO Patent Application WO/2016/148540
Kind Code:
A1
Abstract:
An apparatus for removing self-interference in an environment supporting an FDR method according to the present invention may comprise: an analogue self-interference removal unit that is constructed to remove a first analogue self-interference by subtracting a self-interference signal received through a first delay circuit connected between an RF transmission chain and an RF reception chain of the apparatus from a self-interference signal received at a first circuit of the RF reception chain of the apparatus, and that is constructed to remove a second analogue self-interference by subtracting a self-interference signal received through a second delay circuit connected between the RF transmission chain and the RF reception chain of the apparatus from a self-interference signal received at a second circuit of the RF reception chain of the apparatus; and a processor that is constructed to determine whether the first and the second analogue self-interference removals were respectively successful on the basis of the respective residual self-interference signals that are left after removing the first and the second analogue self-interferences.
