Abstract

In this paper, we analyze the multiuser performance of a modified version of a newly proposed balanced transmitted-reference (TR) system for ultra-wideband (UWB) communications. The proposed TR system is capable of properly eliminating the inter-pulse interference (IPI) between the reference and data pulses in multipath environments, with a low system complexity. We further investigate the effect of the inter-pulse distance on the multiuser capacity and demonstrate the trade-off between the system´s achievable information rate and the number of coexisting users.
