1. A computer-implemented method comprising:
- receiving a first signal from a first receiver, wherein the first signal includes (i) a first principle component generated by a first wireless device and (ii) a first interfering component generated by a second wireless device;
receiving a second signal from a second receiver, wherein the second signal includes (i) a second principle component generated by the second wireless device and (ii) a second interfering component generated by the first wireless device;
forming a first linear equation based, at least in part, on the first signal from the first receiver;
forming a second linear equation based, at least in part, on the second signal from the second receiver; and
simultaneously solving the first linear equation and the second linear equation to (i) decouple the first principle component generated by the first wireless device from the first interfering component generated by the second wireless device and (ii) decouple the second principle component generated by the second wireless device from the second interfering component generated by the first wireless device.

Abstract
A computing system may utilize interfering signals of two or more wireless devices for improving communications involving the two or more wireless devices. These techniques and architectures may allow for improved spectral efficiency that enables a relatively large number of wireless devices to communicate among one another via receivers that share overlapping or adjacent frequencies. Such utilization of interfering signals may help solve a general problem involving, for example, co-channel interference (CCI) arising from densely deployed relatively small wireless communication cells for increasing communication throughput.
