Design of Ultra-Wideband Signal Acquisition Algorithms Under Indoor Channel Conditions

During ultra-wideband high-speed pulse signal reception, the first step is signal acquisition. On the basis of ultra-wideband communication standards, the algorithm of synchronization sequence and frame delimiter detection is designed for the indoor propagation model of ultra-wideband signals, and the simulation results show that the algorithm can achieve more than $99 \%$ of the acquisition rate under the conditions of indoor multipath channel with the signal-to-noise ratio greater than -10dB. The algorithm has stable performance and moderate complexity, and can be used as the basis for the logic development of ultra-wideband receivers.
