The Maximin Algorithm for Adaptive Arrays and Frequency-Hopping Systems.

Abstract

The maximum algorithm adapts the weights of an antenna array to provide simultaneous interference suppression and beamforming in a frequency-hopping communication system. The algorithm is derived and a digital implementation is presented. Simulation experiments illustrate the ability of the maximum algorithm to rapidly form deep nulls in the directions of interference sources. For the full exploitation of an adaptive array for wideband frequency-hopping communications, some form of frequency compensation is necessary. The strengths, limitations, and variations of three methods are examined.
