ABSTRACT:
The present invention concerns a learning sequence for estimating a transmission channel and an estimator device adapted to use a sequence of this kind. The learning sequence for estimating a transmission channel of length L comprises a guard sequence of length L followed by a reference sequence of length N such that its total length N+L is greater than or equal to 2L+1 and such that the transmission matrix A associated with it defined by the product of the Hermitian transpose A.sup.H of the transmission matrix by the transmission matrix A is inversible.
