SYSTEMS AND METHODS FOR CONTROLLING THE TRANSMISSION AND RECEPTION OF INFORMATION SIGNALS AT INTENDED DIRECTIONS THROUGH AN ANTENNA ARRAY

摘要

Systems and methods are disclosed herein for controlling communication of information signals at an intended direction that involves (i) obtaining a set of changing weighting solutions for an antenna array having two or more antenna array elements, each of the weighting solutions defining a set of array weights that generates an imposed error as a function of direction in one or more of amplitude, phase, frequency and polarization of an information signal transmitted or received by the antenna array, wherein the imposed error for all of the changing weighting solutions is substantially the same at an intended direction and varies at unintended directions; (ii) selecting one of the changing weighting solutions; (iii) applying the set of array weights of the selected changing weighting solution to a set of antenna signals corresponding to the information signal transmitted or received through the antenna array elements; and (iv) selecting and applying each of the changing weighting solutions to the set of antenna signals according to a selection change rate, so that the information signal is recoverable at the intended direction and unrecoverable at all unintended directions.

1. A method of controlling communication of information signals at an intended direction through an antenna array, the method comprising:
obtaining a set of changing weighting solutions for an antenna array having at least two antenna array elements, each of the set of changing weighting solutions defining a set of array weights that generates an imposed error as a function of direction in at least one of amplitude, phase, frequency and polarization of an information signal transmitted or received by the antenna array, wherein the imposed error for all of the weighting solutions is substantially the same at an intended direction and varies at unintended directions; selecting one of the set of changing weighting solutions; applying the set of array weights of the selected changing weighting solution to a set of antenna signals corresponding to the information signal transmitted or received through the antenna array elements; and selecting and applying each of the set of changing weighting solutions to the set of antenna signals according to a selection change rate, so that the information signal is recoverable at the intended direction and unrecoverable at all unintended directions.
