The paper considers the time sampling of the a priori probability distribution function of the state of a diffusion process by semigroup decomposition methods. We approximate the semigroup generated by the evolution equation associated to the diffusion by Trotter's formula. We benchmark the approximation against an exact method, viz. the Wei-Norman… (More)
− Super-resolution focusing and nulling experiments are described based on multipath-enhanced time-reversal techniques. Using these techniques, two independent 2.45 GHz signals focused at locations separated by 5 cm at a distance of 6.7 m are successfully demodulated.
We consider the tradeoffs between sensing and communication in a consensus+innovations distributed detection problem when the local communications among agents are noisy. Intuitively, we can expect that the error performance of the distributed detector is affected by both the sensing noise and the noise corrupting the communication among agents in the… (More)
