SYSTEMS/METHODS OF SPECTRALLY EFFICIENT COMMUNICATIONS
First Claim
1. A communications method comprising:
- transmitting by a first wireless transmitter a first signal that comprises a desired component that is related to a desired signal and an interference component that is related to an interference signal;
the desired signal and the interference signal being generated by respective physically distinct desired and interfering sources that are independent of one another;
transmitting by a second wireless transmitter a second signal that comprises a desired component that is related to the desired signal and an interference component that is related to the interference signal; and
concurrently wirelessly receiving at a receiving element the first and second signals, so that respective components thereof that are related to the interference signal at least partially cancel one another at the receiving element.

Abstract
First and second receivers are used to receive respective first and second signals, to process said first and second signals and provide respective first and second measures thereof to respective first and second transmitters. The first and second transmitters are configured to launch the first and second measures, respectively, each comprising a desired component that has originated at a desired source, and an interference component that has originated at an interfering source. The first and/or second transmitters are configured to process and launch the respective first and second measures, properly conditioned, so that upon interception thereof by a receiving element the interference components thereof add destructively and substantially cancel (or at least partially cancel) each other, whereas the desired components avoid substantial cancellation owing to a phase relationship therebetween that differs relative to a phase relationship between the interference components.

9. A communications system comprising:
-
a first receiver that is configured to receive a measure of a desired signal and a measure of an interference signal; a second receiver that is configured to receive a measure of the desired signal and a measure of the interference signal; a first transmitter that is connected to the first receiver and is configured to form and transmit a first signal that is related to the desired signal and interference signal; and a second transmitter that is connected to the second receiver and is configured to form and transmit a second signal that is related to the desired signal and interference signal; wherein the first and second transmitters are configured to transmit the respective first and second signals so that respective components thereof that are related to the interference signal at least partially cancel one another at a receiving element. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
