Abstract

OFDM system suffers from significant performance degradation due to the presence of phase noise, which causes the common phase error (CPE) and intercarrier interference (ICI) among subcarriers. Various phase noise analysis and mitigation schemes were presented for OFDM in the literature, which only concerned with phase noise generated at the receiver, assuming the transmitter noise is negligible. However, this is inappropriate for the uplink application, where transmitter employs relatively low cost local oscillators. In this paper, we aim to analyze an OFDM system with phase noise at both transmitter and receiver in a WSSUS multipath fading channel. Results show that such system is equivalent to an OFDM system with phase noise at receiver only, hence simplifies the system model and provides an easy way to examine phase noise effect at both transmitter and receiver. © 2006 IEEE.
