Claim One:
1. A method for reducing interference in a receiver ( 2 ) comprising at least two antennas ( 4 , 6 ), each receiving a signal transmitted through an associated radio propagation channel, the received signals corresponding with the same emitted signal comprising frames of symbols distributed in time and frequency, among which some symbols, called pilot symbols, are known to the receiver, where the said method comprises the following steps: weighting ( 20 ) of each of the signals received with a weighting vector associated respectively with a respective antenna of the receiver; combination ( 22 ) of the weighted signals received to obtain a combined received signal; weighting ( 24 ) of a reference signal comprising pilot symbols with another weighting vector; comparison ( 26 ) of the combined received signal and the weighted reference signal to obtain an error; and determination ( 28 ) of the weighting vectors with the help of the maximum a posteriori criterion by maximising the probability of realisation of the said weighting vectors conditionally with the error obtained.
