    摘要: Disclosed is a phase noise mitigation method using a MIMO system in which each antenna has an independent oscillator. The phase noise mitigation method includes: receiving a transmission signal transmitted from a transmitting antenna, through a receiving antenna and an oscillator; estimating multiple parameters for a phase noise of a transmission terminal and a phase noise of a receiving terminal on the basis of a result of mathematical modeling of signals transmitted and received through the MIMO system in which each antenna has an independent oscillator; and mitigating phase noises of the transmission terminal and the receiving terminal which are estimated from the received signal.
