Abstract
The present disclosure provides for distortion cancelled by receiving a collided signal, the collided signal comprising a first signal carrying a first packet and a second signal carrying a second packet; amplifying and digitizing the collided signal into a first digital signal at a first gain and a second digital signal at a second gain that is greater than the first gain; determining a nonlinear interference component of the first packet on the second packet from the first digital signal; decoding the first packet from the first digital signal; re-encoding the first packet with a first estimated channel effect into an estimated signal; calculating a linear interference component of the first packet on the second packet from the estimated signal; removing the linear interference component and the nonlinear interference component from the second digital signal to produce a de-interfered signal; and decoding the second packet from the de-interfered signal.
