Blind Synchronization and Demodulation for Noncoherent Ultra-Wideband System with Robustness against ISI and IFI

Synchronization is a crucial task and big challenge for ultra-wideband (UWB) systems, especially in the presence of inter-symbol interference(ISI) and inter-frame interference (IFI). This paper proposes a blind synchronization and demodulation algorithm that is capable of mitigating ISI and IFI for noncoherent UWB system. Employing a series of codeword matching and averaging operations, the proposal can suppress interference and noise effectively. Moreover, it can acquire synchronization rapidly and improve the bit error rate (BER) performance significantly thanks to efficiently exploiting the observed signals. Simulation results demonstrate the substantial performance improvement compared to existing methods.
