1. A method of wireless communication at a receiving device, comprising:
determining a perturbed precoding matrix based on a precoding perturbation rule;
receiving a signal that was generated based on the perturbed precoding matrix; and
subtracting non-linearities from the received signal based on a channel estimation using the perturbed precoding matrix over one or more iterations.
