Abstract

Polynomial cancellation coded orthogonal frequency division multiplexing (PCC-OFDM) with overlapping symbol periods is a modulation technique which overcomes many of the disadvantages of OFDM. PCC-OFDM is much less sensitive to frequency offset and Doppler spread than OFDM. Only the length of the equalizer used limits the delay spread that can be tolerated in a PCC-OFDM system. In this paper expressions are calculated for the intercarrier interference (ICI) and intersymbol interference (ISI) caused by timing errors in PCC-OFDM. Results are presented for simulations of PCC-OFDM in channels subject to frequency error and multipath. It is shown that good performance can be achieved using equalizers of only moderate complexity
