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 RX<SUB>j </SUB>concerned, the method and the module calculate N<SUB>t </SUB>impulse responses in the time domain by multiplying N<SUB>p </SUB>pilot symbols extracted from a frequency-domain signal R<SUP>j</SUP>(n) obtained after demodulation of a time-domain signal received by the receive antenna RX<SUB>j </SUB>concerned 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.
