Multipath propagation and the optimal SNR for adaptive arrays
Mats Viberg · 2003
The author investigates the optimal output SNR (signal-to-noise ratio) for adaptive arrays. His main interest is what happens in the case of coherent multipath propagation. He casts the multipath into a statistical framework and derives an approximation of the average optimal SNR. He concludes that the average optimal SNR increases linearly with the number of reflections of the desired signal. The reason for this is that it is possible for the receiver to take advantage of the extra desired signal energy that comes from the reflections.>
