APPARATUS AND METHOD FOR CANCELLATING SELF-INTERFERENCE AND RELAY SYSTEM FOR THE SAME

摘要

PURPOSE: A relay system for magnetic interference cancellation which accurately eliminates interference with the usage of R-RS is provided to increase the efficiency of frequency use by supporting MIMO(Multi-Input Multi-Output). CONSTITUTION: A transmitter(62) transmits an R-RS(Relay Reference Signal) through the agreement of a base station in a section. The signal is not transmitted in the base station. A receiver(61) acquires SI(Self Interference) channel value from signal with the said reference signal. The transmitting terminal transmits a message signal. The signal is received after the self-interference channel in the reception end.
