Abstract :
This paper presents analysis of a synchronization scheme for a low complexity, noncoherent ultrawideband (UWB) receiver. The receiver has very low complexity and the synchronization scheme does not increase drastically the complexity. A theoretical formula that helps in the definition of the preamble length is proposed and its validity provided for reasonable signal to noise ratio (SNR). The performance is examined in terms of probability of synchronization for both AWGN and Saleh-Valenzuela channel models. The synchronization results together with the BER performance show the suitability of this simple receiver structure for low cost devices in sensor networks.
