Preamble structure and synchronization for IEEE 802.15.6 Impulse-Radio Ultra-Wideband physical layer

The paper develops a method of synchronization for synchronization header (SHR) structure described in the draft of IEEE 802.15.6 standard for body area network (BAN) and its Impulse-Radio Ultra-Wideband (IR-UWB) physical layer (PHY) with differential phase modulation. Uniqueness of this PHY is that transmitted waveform shape is not known to the receiver at the time of synchronization and therefore classic synchronization methods based on correlation cannot be employed. Based on the developed synchronization method, synchronization performances with the different SHR structures are evaluated and solutions are suggested for the SHR structure described in the standard.
