Abstract

A new detection scheme for OFDM signals distorted by a memoryless nonlinear power amplifier is presented. Mitigating the power amplifier nonlinearity in the receiver is referred to as Digital Post-Distortion (DPoD). The new iterative detection scheme, termed Nonlinear Detection (NLD), does not attempt to cancel the nonlinear distortion. Rather, it employs the nonlinear components of the received signal to improve detection assuming that the nonlinear model of the power amplifier is known at the receiver side. The advantages of the proposed technique are demonstrated via simulations.
