Subspace-based DOA estimation using Fractional Lower Order statistics
Direction Of Arrival (DOA) estimation, using a sensor array, in the presence of non-Gaussian noise using Fractional Lower-Order Moments (FLOM)matrices is studied. In this paper, a...

Gradually reconfiguring virtual network topologies based on estimated traffic matrices
Traffic matrix, which is required as an input of traffic engineering (TE) methods, is difficult to be obtained directly. One possible approach to obtaining the traffic matrix is to...
