Abstract
A channel estimation device receives at one end of the channel a training sequence corresponding to a learning sequence produced at the other end of the channel. The estimation device generates a replica of the learning sequence and establishes the correlation of the learning and training sequences in order to produce a set of correlation coefficients. The estimation device includes a corrector device for eliminating the coefficients having the lowest moduli. The criteria used for eliminating the lowest moduli coefficients is that the sum of the squares of the moduli of the eliminated coefficients is less than a fraction of the sum of the squares of the moduli of all the correlation coefficients.
