Abstract
Systems and methods are presented for communication under strong and dynamic co-channel interference, by exploiting temporal self-coherence of complex signals transmitted within a first communication band that is equal to or falls within a second communication band occupied by co-channel interference (CCI). Each complex signal comprises a first signal and at least a second signal that is a phase-shifted replica of the first signal. The communication receiver comprises a plurality of antennas receiving each complex signal substantively under the CCI, and a Dynamic Interference Cancellation and Excision processor that excises the CCI sufficiently to demodulate each complex signal.
Claims24
A receiver, comprising:
- a plurality of antennas configured to receive at least one complex signal, the at least one complex signal being within a first communication band that is equal to or falls within a second communication band of at least one co-channel interference signal, and wherein the at least one complex signal comprises a first signal and a second signal, the second signal comprising at least one component that is a repeat and phase shift of the first signal or a repeat without a phase shift of the first signal;
- a signal processing module configured to perform self-coherence restoral on the at least one complex signal;
- wherein the power of the at least one complex signal is sufficient to allow the signal processing module to receive the at least one complex signal absent the at least one co-channel interference signal.
