A nondata-aided SNR estimation technique for multilevel modulations exploiting signal cyclostationarity
Signal-to-noise ratio (SNR) estimators of linear modulation schemes usually operate at one sample per symbol at the matched filter output. In this paper we propose a new method for...

Local visual homing by matched-filter descent in image distances
Abstract In natural images, the distance measure between two images taken at different locations rises smoothly with increasing distance between the locations. This fact can be exp...

Randomized group testing for acoustic source localization
Undersea localization requires a computationally expensive partial differential equation simulation to test each candidate hypothesis location via matched filter. We propose a met...
