This paper presents a novel approach to automatic speaker recognition using dynamic Bayesian network (DBN). DBNs have a precise and well-understand probabilistic semantics, and it has the ability to incorporate prior knowledge, to represent arbitrary non-linearities, and to handle hidden variables and missing data in a principled way with high… (More)
Cooperative jamming enables secure communication between two radios without using shared secrets. We design an efficient randomized coding scheme that uses cooperative jamming within the context of conventional modulation-demodulation schemes to achieve concurrent two-way secure communication.
