In this work differentially coherent communication schemes for Impulse Radio Ultra-Wideband (IR-UWB) that transmit single uninterrupted package of energy per symbol, expected to be included in the IR-UWB IEEE 802.15.6 wireless Body Area Networks (BAN) standard are considered. Models for two receiver architectures, suitable for such communication schemes and feasible to implement in current CMOS technology - duty-cycled sampling receiver and chirp receiver are derived. After that, two differential detection techniques for employed receiver architectures - ordinary DPSK and Sample-wise DPSK (S-DPSK) are described. Theoretical analysis of probability of error for S-DPSK is also provided. Performances of the sampling and the chirp receiver architectures with DPSK and S-DPSK detection methods employed are analyzed under narrowband and Frequency-Modulated UWB (FM-UWB) types of interference.
