Method and device for synchronizing rectilinear or quasi-rectilinear links in the presence of interference

Abstract From the Canadian patent

A method of synchronizing a substantially rectilinear signal being propagated through an , unknown channel, in the presence of unknown substantially rectilinear interferences, received by an array of N sensors in which a known training sequence s(nT) is used, comprising K symbols and sampled at the symbol rate T (s(nT) 0 <= n , <= K ? 1), characterized in that based on observations x((n + l/p)T) over the duration of the training , sequence, where p = T/Te is an integer and Te the sampling period a virtual , observation , vector X((n + l/p)T) = x((n + l/p)T)T x((n + l/p)T)~ T is defined, as well , as a decision criterion or decision statistic taking into account the second-order …
