The problem of initial acquisition of ultrawideband (UWB) signals in the dense multipath channel is addressed. We demonstrate the advantages of designing the acquisition system so that the size of the uncertainty region is a Fibonacci number and propose a simple search strategy for coarse synchronization that uses no channel knowledge, extending a previous work where we proposed a method based on...
In a previous work the authors proposed a search strategy based on the golden section for coarse acquisition of ultra wideband (UWB) signals in the dense multipath channel. The proposed method achieved practically the minimum mean acquisition time under a simplistic model. In this paper those results are extended by showing that the golden section strategy is especially advantageous when the size...
