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