ABSTRACT
UWB shows great promise for use in a number of wireless communications applications, in particular, short range high bit rate networking.  However, due to the emissions limits set by the FCC, commercial systems are limited in range for high data rates. To achieve greater range, both simple and advanced techniques need to be investigated. This article presents throughput-range analysis for UWB communications systems in conjunction with a N-tap maximal ratio combiner (MRC) and general selection combining, GSC(N, L), receiver structures in Rayleigh fading channels. A trade-off is presented between the receiver complexity and required throughput performance. The analysis is further extended to Nakagami-m fading environment.
