METHOD FOR DETECTING CANCELLATION SIGNAL OF TRANSMISSION LEAKAGE SIGNAL IN A RADIO FREQUENCY TRANSMIT/RECEIVE DEVICE CAPABLE OF IMPROVING THE SIGNAL RECEIVING SENSITIVITY IN A WIRELESS TRANSCEIVER

摘要

PURPOSE: A method for detecting cancellation signal of transmission leakage signal is provided to easily and exactly search a cancellation signal coping with a transmission leakage signal in a radio frequency transmit/receive device.;CONSTITUTION: An inclination of a resultant vector about the detected vector is calculated. It is checked whether the calculated composite vector is converged into a current area or not. If the current area has a declining inclination, the procedure for checking whether the composited vector is converged to the current area or not is repeated one or more times. The cancellation signal coping with the transmission leakage signal is determined using the detected maximum declining inclination.;COPYRIGHT KIPO 2011
