1. A communication method, comprising:

  • receiving at a station a spread signal, wherein the station has a multi-element antenna array with a first set of elements arranged in a spaced vertical direction and a second set of elements arranged in a spaced horizontal direction, and wherein the spread signal is a data signal spread over multiple discrete tones according to a remote spreading code of a remote station;

    adaptively despreading the received signal by using a first despreading code based on characteristics of the received signal at the first set of elements of the array, wherein a vertical displacement of the first set of elements enables the station to perform vertical beam steering; and

    adaptively despreading the signal received by using a second despreading code based on characteristics of the received signal at the second set of elements of the array, wherein a horizontal displacement of the second set of elements enables the station to perform horizontal beam steering.
