Abstract - Polynomial cancellation coded orthogonal
frequency division multiplexing (PCC-OFDM) with
overlapping symbol periods is a modulation scheme with
properties that make it well suited to high speed data
transmission including mobile applications. PCC-OFDM
is much less sensitive to frequency offset and Doppler
spread than ordinary OFDM. Equalizers to counteract
multipath transmission are much simpler for PCC-OFDM
than for single carrier systems or for OFDM systems
without a cyclic prefix. In this paper PCC-OFDM in
combination with code division multiple access (CDMA)
for a downlink is considered. It is shown that the proposed
