Synchronization of UWB signals in the dense multipath channel based on the golden section

The problem of coarse synchronization of Ultra Wideband signals in the dense multipath channel is addressed. When the classical correlation-based approach is used with this type of channel, a search strategy for the region of uncertainty of the random delay should be chosen. We consider a simplified situation, since our purpose is precisely the analysis of the possible search strategies. Comparison of a novel strategy based on the golden section and another efficient one shows that none of them is optimum from the point of view of the mean acquisition time. The golden section method, however, has a smaller complexity in the general case.
