METHOD AND DEVICE FOR SYNCHRONIZING RECTILINEAR OR QUASI-RECTILINEAR LINKS IN THE PRESENCE OF INTERFERENCE

摘要

The invention concerns a method for synchronizing a substantially rectilinear signal propagated through an unknown channel, in the presence of substantially rectilinear unknown interference, received by a network of N sensors, wherein a known learning sequence s(nT) of K symbols and sampled at a symbol rhythm T(s(nT), 0 = n = K - 1) The invention is characterized in that it consists in defining from observations x((n + Up)T) over the duration of the learning sequence, where p = T/Te is an integer and Te the sampling period, a virtual observation vector X((n + Up)T) = [x((n + l/p)T)<SUP>T</SUP>, as well as a decisional or decisional statistics criterion taking into account the non-circular character of the order of 2 of the interference, using the first and second correlation matrices of the virtual observation vector X((n + Up)T).
