Popis:	Impulse radio (IR) ultra wide band systems (UWB) by nature require an accurate timing. This contribution proposes three digital algorithms for compensating the time jitter resulting from the oscillator driving the receiver sampler. The main idea is to estimate jointly useful data and a fraction of the time jitter by using coloration properties of the oscillator phase noise. A maximum likelihood (ML) estimation based algorithm, a suboptimal but with lower complexity one and corresponding adaptive versions are detailed.
