Self-interference cancellation method and apparatus of relay using the same frequency band in OFDM-based radio communication system

摘要

Provided is a self-interference cancellation method and apparatus that may remove self-interference occurring when a transmission signal of a transmit antenna is received, directly or via a reflector, by a receive antenna in a relay using the same frequency band in an orthogonal frequency division multiplexing (OFDM)-based radio communication system.
