How to Switch a Beam-Forming Network with Minimum Disturbance to Existing Communication Channels.

reportActive / Technical Report | Accession Number: ADA025208 | Open PDF

Abstract:

A beam-forming network BFN consisting of a tree of variable power dividers VPDs is typically used to divide the power among beams in a multiple-beam antenna. During the changeover from one set of beam configurations to another it is important that a user who is present in both configurations does not have his communication channel disturbed. A procedure is presented for systematically changing the VPDs, first to an intermediate configuration, and then to a final configuration, which avoids any disturbance to continuing users. Author
