On a maximum likelihood delay acquisition algorithm
Hatem Boujemâa, Mohamed Siala · 2002
In this paper, a maximum likelihood delay acquisition algorithm is proposed. It consists in minimising the mean square error between the received signal and an estimated one based on a number of paths and a set of delay hypotheses. Unlike the conventional acquisition algorithm, the proposed approach is able to detect, with high probability, paths with delays as close as one fourth of the chip period.
