UWB technology: chaotic communications versus noncoherent impulse radio

The IEEE 802.15.4a task group for wireless personal area networks (WLANs) is working on an ultra-wideband radio (UWB) standard for the indoor radio applications. Among the modulation schemes proposed, the noncoherent impulse radio and chaotic frequency modulated differential chaos shift keying (FM-DCSK) modulation schemes belong to the class of transmitted reference (TR) systems. This paper proposes a unified theory for the TR systems that makes possible the comparison of the FM-DCSK and noncoherent impulse radio systems, gives an exact expression for the noise performance of generalized TR system and determines the feasibility of an FM-DCSK UWB radio system.
