On the Blind Estimation of Chip Time of Time-Hopping Signals Through Minimization of a Multimodal Cost Function


In this correspondence, we focus on blind estimation of the chip duration of time-hopping signals by introducing a cost function based on time-of-arrival (ToA) folding over multiple observation sets. An optimization algorithm that takes advantage of the highly oscillatory behavior in the nearby of the global minimum is proposed and a performance bound for… (More)
