Time and Frequency Domain Adaptive Algorithms for Approximating the Filtering Operations in an Optimum Multibeam System.

Abstract

The purpose of this memorandum is to derive several adaptive algorithms for approximately realizing the matrix filtering operation prior to beamforming which is utilized by a wide class of 'optimum' multibeam detection and estimation systems. The 'optimum' array systems that are referred to here generally assume a plane wave signal or some known linear transformation of a plane wave signal or some known linear transformation of a plane wave signal, stationary input processes, and an observation interval which is long compared to the maximum interval of significant correlation of the input processes. A wide variety of estimation and detection criteria have been investigated under these assumptions; the filtering and beamforming operations have been shown to all fit into the compact cannonical form.
