Abstract

Polynomial cancellation coding (PCC) is a coding method for orthogonal frequency division multiplexing (OFDM) in which the information to be transmitted is modulated onto weighted groups of subcarriers rather than onto individual subcarriers. It has previously been shown that PCC substantially reduces the sensitivity of OFDM to carrier frequency offset. In this paper, it is shown that PCC also reduces the intercarrier interference (ICI) due to Doppler spread. Results are presented for a frequency non-selective i.e. flat fading channel, subject to classical Doppler spread. By using weighted pairs of subcarriers the ICI due to Doppler spread can be reduced by approximately 15 dB. By using weighted groups of three subcarriers a further 15 dB reduction in ICI can be achieved
