Communicating distinct data over a single frequency using multiple linear polarized signals

摘要

A method and system for transmitting three distinct electromagnetic signals on a same frequency are provided. One or more transmitting devices transmit a first data signal and an inverse of the first data signal in two orthogonal linear polarities of an antenna maintaining their inverted phase relationship and a same amplitude as propagated. Transmitting devices also transmit a second data signal in a linear polarity with a 45 degree rotation around the transmit axis of the first data signal. Transmitting devices also transmit a third data signal in linear polarity orthogonal to the second data signal and consequently 315 degree rotation around the transmit axis from the first data signal.

1. A method for transmitting electromagnetic signals, comprising:
providing said electromagnetic signals conveying first data and second data, wherein said electromagnetic signals are of a same frequency, and wherein said electromagnetic signals comprise a first data signal conveying said first data and a second data signal conveying said second data; transmitting said first data signal and an inverse of said first data signal respectively in two orthogonal linear polarities of a linear polarization scheme so as to maintain their inverted phase relationship once propagated; and transmitting in a linear polarity said second data signal in a power null of said transmitted first data signal and said transmitted inverse of said first data signal.
