Radio Interferometers with wide bandwidths
The Australia Telescope Compact Array and the Very Large Array are currently being upgraded to operate with wide bandwidths; interferometers dedicated to the measurement of cosmic microwave background anisotropies are being designed with large instantaneous bandwidths for high sensitivity. Interferometers with wide instantaneous bandwidths that do not operate with correlators capable of decompo...
متن کاملResource Management in Wide-Area ATM Networks using Effective Bandwidths
This paper is principally concerned with resource allocation for connections tolerating statistical quality of service (QoS) guarantees in a public wide-area ATM network. Our aim is to sketch a framework, based on eeective bandwidths, for call admission schemes that are sensitive to individual QoS requirements and account for statistical multiplexing. We begin by describing recent results appro...
متن کاملOptimal total exchange in linear arrays and rings
In this paper we consider the problem of total exchange (or multi-scattering) in the context of linear arrays and rings. Such a communication mode occurs when each node has a distinct message to send to every other node in the network. The problem has been studied extensively, although no optimal algorithm has been proposed for the two networks of interest. We present simple algorithms for the ...
متن کاملRobust Adaptive Beamforming for Wide-Band, Moving, and Coherent Jammers via Uniform Linear Arrays
The problem of providing robustness to the conventional narrow-band uniform linear array configuration so as to handle wide-band and moving jammers is addressed here. This robustness is achieved via the use of derivative constraints in jammer directions. However, since the jammer directions are not known a priori, these constraints are incorporated with a maximum likelihood characterization of ...
متن کاملOptimal Resource Allocation in Random Networks with Transportation Bandwidths
We apply statistical physics to study the task of resource allocation in random sparse networks with limited bandwidths for the transportation of resources along the links. Recursive relations from the Bethe approximation are converted into useful algorithms. Bottlenecks emerge when the bandwidths are small, causing an increase in the fraction of idle links. For a given total bandwidth per node...
