Abstract
The effect of direct current (DC) offset on orthogonal frequency division multiplexing (OFDM) system with zero-padded (ZP) suffix is analysed in this paper. It is found that the ZP appended OFDM system suffers more from DC offset than a cyclic prefix inserted OFDM system and even demonstrates bit error flooring if the DC power exceeds a maximum allowed threshold. Simple algorithms are also proposed for DC offset estimation and compensation. The analysis is confirmed by simulation using multiband OFDM specification for ultra-wideband application.
