Abstract
A micro-diverse directional antenna array positioned proximately upon the boundary of a convex shape whereby the primary attenuation lobes of neighboring antennae overlap. This creates a situation in which the reception of signals by said array from the space-time-delay domain of transmission can be effectively modeled as a banded linear transformation upon discretized space-time-delay domain of transmission yielding the antenna reception at discrete time steps.

21. A communications device for use with users transmitting in a communication medium with user transmissions characterized by time-propagation displacement and location displacement as a function of a user location relative to a communications device location, the communications device comprising,
an antenna collection including two or more directional antennae where each antenna is defined by a base location vector, an attenuation function having a contour map and an antenna orientation direction vector lying in the contour map and where each antenna connects to an antenna interface circuit having time steps which generates quantities over time intervals based upon received user transmissions and wherein the contour map for one of the directional antennae overlaps the contour map of another one of the directional antennae whereby the received user transmission at said two or more antennae are linearly related, said antenna collection having said two or more directional antennae with base location vectors proximate to a common boundary of a shape in two or more dimensions, said antenna collection having a collection center wherein the base location vector for each of said antenna is a distance from said collection center which is small compared with the distance traveled by user transmissions propagating in the communications medium within the time step of the antenna interface sampling circuitry and wherein the antenna orientation direction vector for each of said antenna has a location measure in one or more dimensions relative to the antenna collection center, one or more information processors receiving the antenna generated quantities for each time step of the interface circuit for each of the antennae to provide discrete time-propagation displacements and discrete location displacements, and said information processors transforming a linear combination of said discrete time-propagation displacements and said discrete location displacements to form transformed combinations providing user location information.
