Multipath time-delay estimation via the EM algorithm
MetadataShow full item record
We consider the application of the EM algorithm to the multipath time delay estimation problem. The algorithm is developed for the case of deterministic (known) signals, as well as for the case of wide-sense stationary Gaussian signals.

Biases in Thorpe-scale estimates of turbulence dissipation. Part I : Assessments from large-scale overturns in oceanographic data Mater, Benjamin D.; Venayagamoorthy, Subhas K.; St. Laurent, Louis C.; Moum, James N. (American Meteorological Society, 2015-10)Oceanic density overturns are commonly used to parameterize the dissipation rate of turbulent kinetic energy. This method assumes a linear scaling between the Thorpe length scale LT and the Ozmidov length scale LO. Historic ...
