Sampling Frequency Optimisation and Nonlinear Distortion Mitigation in Subsampling Receiver

Subsampling receivers utilise the subsampling method to down convert signals from radio frequency (RF) to a lower frequency location. Multiple signals can also be down converted using the subsampling receiver, but using the incorrect subsampling frequency could result in signals aliasing one another...
