摘要： This interference reduction method in a receiver (2) comprising at least two antennas (4, 6), each receiving a signal transmitted through a radio propagation channel, 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 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.
