Orthogonal Frequency Division Multiplexing (OFDM) is a kind of modulation technology with strong resistance to frequency selective fading and high frequency spectrum utilization. It is a kind of multi-carrier transmission scheme with the lowest implementation complexity and the most widely used. However, the whole OFDM system is particularly strict on the orthogonality between subcarriers. Any small carrier frequency offset will destroy the orthogonality between subcarriers, so it is sensitive to local oscillator phase noise. This paper analyzes and summarizes the existing phase noise optimization research, and a phase noise optimization algorithm based on feedback decision is proposed. Through the simulation of phase noise elimination algorithm at the receiver, it is verified that the phase noise of OFDM system can be suppressed.
