As compared to coherent detection algorithms, the energy-detection (ED) based algorithm is more vulnerable to noise and narrowband interferences (NBIs) when detecting IR-UWB signals. Various nonlinear signal processing (NSP) technologies have been developed to mitigate the destructive effects of NBIs. In this paper, when strong NBIs present, the time and frame synchronization of the IEEE 802.15.6 IR-UWB physical layer is investigated by employing both the conventional ED-based algorithm and the one enhanced with an NSP technology. Computer simulation results show that with the existence of strong NBIs, the conventional ED-based algorithm cannot reduce synchronization errors to an acceptable level, but the NSP-enhanced one can achieve an excellent performance.
