1. A non-transitory computer-readable medium storing a program, wherein the program, when executed, causes a computer to perform a full-duplex self-interference weakening operation, the operation comprising:
separately receiving, by a first port of a dual-polarized receive antenna and a second port of the dual-polarized receive antenna, a signal sent by a transmit antenna;
adjusting the signal received by the first port of the dual-polarized receive antenna, wherein the adjusting the signal received by the first port of the dual-polarized receive antenna comprises:
adjusting at least one of a phase or an amplitude of the signal received by the first port of the dual-polarized receive antenna; and
combining the adjusted signal with the signal received by the second port of the dual-polarized receive antenna.
