Abstract
A method for synchronizing in a receiver an IR-UWB signal including data packets having a first preamble portion of at least two sequences of N pulses spaced by period T and each equal to a reference pulse weighted by a complex coefficient c, n=0 to N−1 indicating the rank of the pulse in the first sequence, and a second preamble portion of at least two sequences equal to the complex conjugate of the first sequence, includes: considering NP successive samples s, for n=0 to NP−1, of a slice, of duration NT, of the first and respectively second preamble portion of a received packet, determining the sequence of values and respectively the sequence of values with Tthe sampling period T=P×T; determining the frequency fand fof the sequence xand y, respectively; and computing shift Δf applied to synchronize to the received signal.
