Impulse radio ultra-wideband (IR-UWB) is a radio technology that transmits information over a broad bandwidth, and which can receive narrowband signals from existing wireless systems with narrowband interference. In this study, a novel synchronisation algorithm is proposed for the IR-UWB receiver, targeting the IEEE 802.15.6 Standard according to the characteristics of the Kasami sequence in the UWB synchronisation header. A Kasami sequence, which is selected as the template, is multiplied by the received signal. The simulation results demonstrate that the proposed algorithm has a higher synchronisation success rate and lower complexity compared with other algorithms that focus on the IEEE 802.15.6 protocol.
