Abstract: Polynomial cancellation coded
orthogonal frequency division multiplexing
with overlapping symbol periods (Overlap
PCC-OFDM) is a modulation technique that is
less sensitive to frequency errors and more
robust against multipath distortion than
OFDM. A cyclic prefix is no longer needed.
However, fading is still a problem and will
cause bit errors. Error propagation will occur
as decision feedback equalizer is used. In
previous studies this was not taken into
account and perfect decisions were assumed.
In Overlap PCC-OFDM because the equalizer
output is a vector rather than a scalar, error
