The invention relates to method for demodulating a signal in a receiver including at least two antennas, each receiving a signal (s1; s2), the received signals (s1; s2) corresponding to a single emitted signal (s) including symbol frames in which certain symbols, referred to as driver symbols, are known to the receiver, the method including the steps of: noise whitening in order to form two combined signals, (c1; c2) the noise components of which are separate; normalizing the noise components of the combined signals (c1; c2) in order to form two signals, the noise components of which are separate and have equal average standards; and performing signal demodulation with the maximum combination of the signal-to-noise ratio on the two signals, the noise components of which are separate and which have equal average standards, characterised in that during the first noise-whitening step for forming the two combined signals, (c1; c2) the latter are determined retroactively using the maximum criterion. |
