Improved spatial smoothing technique
K.W. Cheung, Ross Murch · Electronics Letters · 1997
The authors present a spatial smoothing technique which can be considered as being an improvement on two spatial smoothing techniques developed previously. To verify its usefulness, our improved technique and those previously developed are applied to decorrelate coherent multipath signals in the context of indoor radio channels. The multipath arrival times are then super-resolved using forward-backward (FB) MUSIC and the results are compared to determine the improvement.
