Abstract:
A method for reducing or eliminating an interference signal includes: coupling a transmission signal transmitted from a transmission antenna of a communication device so as to obtain a reference signal; adjusting a power and a phase of the reference signal, superimposing a cancellation signal obtained by the adjusting with a received signal received by a reception antenna of the communication device, and coupling the obtained superposition signal so as to obtain an acquisition signal; and repeating the adjusting until a voltage value of the acquisition signal is smaller than or equal to a historical minimum voltage value, the received signal including a useful signal and an interference signal formed by the transmission signal at the reception antenna; and determining the obtained superposition signal as a received signal for eliminating interference of the receive antenna, the received signal for eliminating interference of the receive antenna including the useful signal.

Claim (Index 1):
An apparatus configured to reduce or eliminate an interference signal, the apparatus comprising: a first coupler, an adjusting portion, a combiner, a second coupler, and a control portion, wherein:\n the first coupler is coupled to a transmission antenna of a communication device, and is configured to couple a transmission signal transmitted by the transmission antenna of the communication device so as to obtain a reference signal; the adjusting portion is coupled to the first coupler and configured to adjust a power and a phase of the reference signal to obtain a cancellation signal; the combiner is coupled to the adjusting portion and a reception antenna of the communication device respectively, and is configured to superimpose the cancellation signal obtained by the adjustment with a received signal received by the reception antenna of the communication device to obtain a superposition signal, the received signal comprising a useful signal and an interference signal formed by the transmission signal at the reception antenna; the second coupler is coupled to the combiner and configured to couple the obtained superposition signal so as to obtain an acquisition signal; and the control portion is coupled to the second coupler and the adjusting portion respectively, and configured to: control the adjusting portion to adjust the power and the phase of the reference signal according to a voltage value of the acquisition signal until the voltage value of the acquisition signal is smaller than or equal to a historical minimum voltage value; and determine the obtained superposition signal as a received signal for reducing or eliminating interference of the reception antenna, the received signal for reducing or eliminating interference comprising the useful signal.
