Abstract
Timing acquisition is performed. A first portion of a preamble having an end is sampled. A first phase value is determined based on the sampled first portion. A second portion of the preamble is sampled and a second phase value is determined based on the sampled second portion. An end phase value is extrapolated based at least in part the first phase value and the second phase value. A clock is adjusted using the extrapolated end phase value.
