摘要：The invention relates to a control signal for receivers, said control signal beingformed by juxtaposing two signal elements of equal duration, and time symmetrical. Forexample, the signal comprises at least one first pseudo-random noise digital sequences(N.sub.s -1) to s(0) and, periodically, at least one second digital sequence s(N.sub.s - 1) tos(0), corresponding to the inverse, obtained by time symmetry, of said first sequence. Thesignal may be used in particular for performing time and frequency synchronization onreceivers and/or for equalizing signals received by said receivers. The invention alsorelates to methods and apparatuses that use said signal.
