Abstract
A method and a module for estimating transmission channels in a multi-antenna system. A matrix A is calculated which is constructed in the form of blocks from training sequences and an appropriate Fourier matrix. For a receive antenna RXconcerned, the method and the module calculate Nimpulse responses in the time domain by multiplying Npilot symbols extracted from a frequency-domain signal R(n) obtained after demodulation of a time-domain signal received by the receive antenna RXconcerned by a product of matrices comprising the pseudo-inverse matrix of the product of the Hermitian matrix of the A matrix with the A matrix enabling decorrelation of modulated carriers adjacent null carriers.
