Full-duplex self-interference weakening method and full-duplex self-interference weakening system

An apparatus, comprising:

• at least one processor configured to:
• separately receive, from 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;
• adjust 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
• combine the adjusted signal with the signal received by the second port of the dual-polarized receive antenna.
