Abstract:
1. A method for transmission of a signal from a plurality of antennas, in a frequency band, said method comprising: splitting said frequency band into a plurality of at least one group of subcarriers; and transmitting on each of said at least one group of subcarriers from said plurality of antennas, simultaneously, using a one or two dimensional precoder, wherein said precoder is a complex weight specific to said plurality of antennas and said group of subcarriers, wherein said complex weight further relies on at least one of a time index of said at least one group of subcarriers; and a frequency index of said group of subcarriers, wherein said frequency band is divided into a plurality of frequency partitions, wherein said plurality of frequency partitions are further divided into a plurality of frequency sub partitions, and wherein said plurality of sub partitions comprise of a plurality of Physical Resource Units (PRUs) and said plurality of PRUs are further divided into a plurality of subcarriers.
