Recently proposed transmitted reference pulse cluster (TRPC) signaling has a more compact and uniform spacing for the reference and data pulse and therefore solves the implementation problem caused by the long delay line requirement in the conventional transmitted reference (TR) ultra-wideband (UWB) system. However, this compact and uniform spacing for the reference and data pulse in the TRPC signaling structure is critical to the inter pulse interference (IPI) of TRPC, which is not studied in the literature. In this paper, the impact of the delay time for the TRPC UWB system is analyzed based on different channel scenarios. Through the Monte Carlo simulations, it is verified that increasing the uniform spacing interval between the reference and data pulse in the TRPC structure can reduce the IPI dramatically and improve the system performance especially at high SNR conditions.
