Abstract :
The performance of a single-user, ultra-wideband (UWB) communication system employing binary block-coded modulation with pulse-position modulation (PPM) or on-off keying (OOK) and operating in indoor multipath channels is considered. We examine the tradeoff between receiver complexity and performance for the case of RAKE receivers with maximal-ratio combining (MRC). The derived expressions are evaluated numerically with measured UWB channel data for various cases.
