PHASE NOISE COMPENSATION RECEIVER

摘要

PROBLEM TO BE SOLVED: To provide a phase noise compensation receiver capable of realizing high-reliability high-speed signal transmission with less amount of calculation by using linear signal processing on frequency domain.SOLUTION: A phase noise compensation receiver for receiving an orthogonal frequency-division multiplexing (OFDM) signal includes: a phase noise compensation coefficient estimation circuit 145 for estimating a phase noise compensation coefficient using a known pilot signal included in an OFDM symbol and a replica signal; and a phase noise compensation circuit 140 for compensating phase noise of a local oscillator included in a reception signal by synthesizing three adjacent reception subcarrier signals after channel equalization, using the phase noise coefficient.SELECTED DRAWING: Figure 2
