Performance of Ultra-Wideband Transmission with Pulse Position Amplitude Modulation and RAKE Reception

Abstract

Recently, pulse position amplitude modulation (PPAM) has been proposed for Ultra-Wideband (UWB) communication systems. PPAM combines pulse position modulation (PPM) and pulse amplitude modulation (PAM) to provide better performance and higher system capacity with low computational complexity. A RAKE receiver can make use of the rich multipath of UWB systems to improve system performance and capacity. In this paper we present the performance of a RAKE receiver employing maximal ratio combining (MRC) in a time hopping (TH) UWB system with PPAM modulation. Performance in a practical multipath fading channel is considered. The error probability and a union bound on performance are derived for a block fading environment. Numerical results are given to illustrate the system performance.
