The Performance of PCC-OFDM in Multipath
Fading Channels
Kusha R. Panta, Himal A. Suraweera and Jean Armstrong
Abstract--Polynomial cancellation coding (PCC) is a very effec-
tive technique that reduces the sensitivity of orthogonal frequency
division multiplexing (OFDM) to frequency errors at the cost of re-
duced spectral efficiency. This paper investigates the effect of PCC
on the fading characteristics of multipath channels and on the er-
ror performance OFDM in a two-path fading channels. Channel
coding is employed for forward error correction (FEC). It is shown
that PCC improves the error performance of OFDM. Moreover,
the overall effect of PCC and the channel coding is taken into con-
sideration while analyzing the spectral efficiency of OFDM.
Index Terms--Orthogonal frequency division multiplexing, fad-
ing channels, polynomial cancellation coding, error performance.
