dc.description.abstract In Cyclix Prefix OFDM (CP) systems, synchronization to the maximal multipath signal generally causes no problem, however, inter carrier interference (ICI) will be introduced in Zero-padding OFDM (ZP-OFDM) systems, e.g, multiband OFDM UWB (MB-OFDM) systems. In this paper, based on the overlap-and-add (ZP-OFDM-OLA) method typically applied in MB-OFDM, we analyze the cause of the ICI and the performance degradation due to the ICI. The expressions of the channel estimation error, signal-to-noise ratio and ICI are derived. Simulation results are also provided, which show good match with the theoretical results. en_AU
