Abstract

Phase noise, introduced by the receiver local oscillator, has severe effects on the performance of orthogonal frequency division multiplexing (OFDM) systems. The common compensation method can only correct common phase error (CPE) caused by the low-frequency part of the phase-noise spectrum, and cannot compensate phase noise thoroughly. A new method, per-symbol phase noise detection and compensation method, is proposed. Based on a frequency-domain linearized parametric model for phase noise, the method not only deals with CPE more effectively, but also compensates most of the intercarrier interference (ICI) induced by the high-frequency part of the phase-noise spectrum. This method well compensates phase noise in higher SNRs and lower quality tuners.
