Abstract :
Pseudo-chaotic time hopping (PCTH) is a recently proposed coding/modulation scheme for UWB (ultrawide band) impulse radio. PCTH exploits concepts from symbolic dynamics to generate aperiodic spreading sequences. In this paper we present a power saving strategy for a multi-access UWB system based on PCTH. It is shown that our approach leads to a significant power saving. The trade-off with respect to BER performance is also discussed.
