Communicating distinct data using polarized data signals
First Claim
1. A method of wirelessly communicating distinct data over a same frequency using polarized data signals, comprising the steps of:
- providing a plurality of data signals conveying information, wherein said data signals comprise a first data signal conveying first data, a second data signal conveying second data, and a third data signal and an inverse of said third data signal conveying third data, wherein said data signals are of said same frequency;
polarizing said first data signal and said second data signal in opposite polarities of one of a first polarization scheme and a second polarization scheme, and polarizing said third data signal and an inverse of said third data signal in opposite polarities of other of said first polarization scheme and said second polarization scheme, wherein said third data signal, and inverse of said third data signal are transmitted along a same transmission path transmitting said third data signal and said inverse of said third data signal in said first polarization scheme from one transmitting station; and
transmitting said polarized first data signal and said polarized second data signal from one of said one transmitting station and other transmitting stations along one of said same transmission path and/or proximate transmission paths, to one or more receiving stations; and
receiving said transmitted data signals in said first polarization scheme and said second polarization scheme at said one or more receiving stations, wherein said first data, said second data, and said third data are obtained from said received data signals comprising said first data signal, said second data signal, said third data signal and an inverse of said third data signal;
whereby amount of distinct data transmitted to said receiving stations over said same frequency is increased.

Abstract
A method and system is provided for communicating distinct data over a single frequency using multiple polarized data signals. Data signals of the single frequency conveying first data, second data, and third data are polarized in a first polarization scheme and a second polarization scheme. The data signals comprise a first data signal, a second data signal, a third data signal, and inverse of the third data signal in a first configuration or a second configuration. The polarized data signals are transmitted from transmitting stations to one or more receiving stations. The first data, second data, and third data are obtained from the data signals received at the receiving stations using an antenna of a first polarity and an antenna of a second polarity. The amount of distinct data transmitted over the single frequency is increased by, for example, about 50% without causing interference between the data signals.
