Abstract
The invention concerns a method of receiving a signal transmitted by a transmitter (k) and arriving at an array of antennae (300) after propagating along a plurality of paths (i), comprising a filtering step (310k) decomposing each antenna signal into separate signals (xl,i,k) issuing from the different paths, a combination step (320k) linearly combining the said separate signals by means of a set of complex coefficients in order to supply a combined signal (zk), the method being characterised in that an error signal (εk) is formed (331k) between a reference value (qk) of the transmitted signal and the said combined signal and in that the set of complex coefficients is adapted (330k) so as to minimise the root mean square of the signal error.
