Title: METHOD FOR REMOVING SPATIAL AND TEMPORAL MULTI-PATH INTERFERENCE FOR A RECEIVER OF FREQUENCY-MODULATED RADIO SIGNALS
Abstract:
Method for decreasing multi-path interference, for a vehicle radio receiver comprising at least two radio reception antennas (A1, A2) that each receive a plurality of radio signals (X1,n, X2,n) composed of temporarily shifted radio signals resulting from a multi-path effect, said plurality of radio signals being combined to deliver a combined radio signal yn to be reconstructed, with: (I) at the time n, where X1, X2, respectively, is a vector, the components of which correspond to the plurality of signals received by the first antenna (A1), the second antenna (A2), respectively, (II) and (III) are scalars, the components of which are complex weights of a spatial filter and (IV) is the transpose matrix of a vector, the components of which are complex weights of a temporal filter, said method comprising implementing an iterative matching algorithm to determine said complex weights of the spatial filter and said complex weights of the temporal filter.
