Abstract
The present disclosure provides for distortion cancellation by receiving a collided signal, the collided signal comprising a plurality of signals that each carry a corresponding packet; for a first signal of the plurality of signals that includes a first packet: amplifying and digitizing the collided signal into a first digital signal at a first gain; and decoding the first packet from the first digital signal; for each signal of the plurality of signals other than the first signal, carrying a given packet: estimating a given linear interference component and a given nonlinear interference component of one or more prior packets to the given packet on the collided signal; removing the given linear interference component and the given nonlinear interference component from the collided signal to produce a given de-interfered signal; and decoding the given packet of the plurality of packets from the given de-interfered signal.
