Abstract
This method for the estimation of a channel between an emitter and a receiver, where the said emitter emits a signal comprising symbol frames distributed in time and frequency, among which pilot symbols known to the receiver, is characterized in that it comprises the following steps: •—computation (30) of a covariance matrix MF and MT of the channel in the frequency and time domains respectively; •—decomposition (32) of the covariance matrices MF and MT into eigenvectors according to the relations MF−WFHNFWF and MT−WTHNTWT; •—computation (34) of the Kronecker product of the matrices NVF and WT to obtain an eigenvector matrix W; •—computation (34) of a diagonal eigenvalue matrix N equal to the Kronecker product of the eigenvalue matrices NF and NT; and •—estimation of the channel with the help of pilot symbols and matrices W and N using the maximum a posteriori or quadratic error minimisation criterion.
