Abstract: In this paper, several aspects of IEEE 802.15.6 DPSK IR-UWB physical layer for usage in the medical BAN are examined. First, the types of the waveforms used in the standard are given. After that we describe the packet structure. We also provide mathematical analysis of two receiver structures: the duty-cycled sampling receiver and the chirp receiver is provided with suitable digital detection methods definitions and analysis. The paper continues with developing a method of synchronisation for preamble structure described in the standard draft together with the synchronisation frame delimiter (SFD) detection method. Preamble structure itself is discussed together with offering an alternative that has better performance with less computational complexity. The performances of receivers designed according to specifications given in the paper are simulated in multi-BAN environments in order to verify robustness of such BAN devices to interference from co-located BANs, essential for the application of this physical layer in the medical BAN.
