Effects of Phase Noise on Performance of OFDM Systems Using an ICI
Cancellation Scheme
Jinwen Shentu, Kusha Panta, and Jean Armstrong
Abstract--This paper investigates the effects of phase noise on
the performance of Orthogonal Frequency Division Multiplexing
(OFDM) systems using an Intercarrier Interference (ICI) cancel-
lation scheme. In this case, the Common Phase Error (CPE) and
ICI caused by phase noise depend on the overall spectrum of each
weighted group of subcarriers rather than on the spectrum of each
individual subcarrier. This means that the system performance can
be improved by filtering the phase noise to fit a particular spec-
trum. It is shown that the ICI cancellation scheme can significantly
improve the Bit Error Rate (BER) performance in the presence of
phase noise.
Index Terms--Intercarrier interference (ICI), orthogonal
frequency division multiplexing (OFDM), phase noise.
