UWB energy detection receivers with partial channel knowledge

This paper deals with energy detection receivers for ultra-wideband systems operating in a dense multipath environment. For binary PPM modulation we propose a novel detection scheme that exploits some information on the channel energy-delay profile. We show that the BER performance of this detector is superior to that of a conventional scheme operating with no knowledge of the channel response. A simple method for estimating the channel delay profile is discussed and it is shown that the impact of the estimation errors on the receiver performance is negligible.
