In this paper, performance and parameter optimization of RAKE reception for time-hopping Ultra Wideband (TH-UWB) systems is investigated when interchip interference (ICI) is taken into consideration. For a TH-UWB system, ICI is closely related to the relationship between the number of chips in a frame (Nc), and the period of the TH code (Nf). In a fixed data-rate case, larger Nf implies higher transmitted symbol signal-to-noise ratio (SNR) and larger ICI in RAKE fingers. So there is a tradeoff...[Show more]
