Estimation of Spherical Wave Coefficients from 3D Positioner Channel Measurements

Electromagnetic vector spherical waves have been used recently to model antenna channel interaction and the available degrees of freedom in MIMO systems. However, there are no previous accounts of a method to estimate spherical wave coefficients from channel measurements. One approach, using a 3D positioner, is presented in this letter, both in theory and practice. Measurement results are present

Distributed resource management using iterative gradient update synthesis

We consider load balancing on a network. Servers of limited bandwidth move a single commodity through a network of buffers (or queues) while external random processes generate and consume this commodity. Our contribution is a distributed algorithm for regulating the backlogs of these queues to a given reference while balancing the mean flow in the network. We formulate this as a fluid buffer regu
