How to switch a beam-forming network with minimum disturbance to existing communication channels
Abstract
A beam-forming network (BFN) consisting of a tree of variable power dividers (VPD's) 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 VPD's, first to an intermediate configuration, and then to a final configuration, which avoids any disturbance to continuing users.
