Title: MMSE receivers for non-linearly distorted OFDM signals
Issue Date: 2009
Abstract: In this paper, we have derived the structure of theminimum mean-squared error (MMSE) receiver for non-linearlydistorted orthogonal frequency division multiplexer (OFDM) signalsin additive white Gaussian noise (AWGN). We demonstratethat this receiver consists of a set of correlators or a set offilters matched to every possible frequency components in thenon-linearly distorted OFDM signal followed by a simple lineartransformation. Simulation results show that the MMSE receiveroutperforms the conventional one, particularly in the presenceof strong nonlinearities. Finally, we conjecture that this receiveris useful in OFDM based fiber-radio applications.
