| Abstract | Orthogonal frequency division multiplexing (OFDM) is widely used in broadband wireless communications systems because of its high resilience to frequency-selective fading and its low implementation complexity. Phase noise (PN) is one of the major RF impairments in direct-conversion wireless transceivers. In this paper, we analyze the impact of PN on an OFDM transceiver. We derive an exact normalized mean square error (NMSE) expression under receive-side PN and examine asymptotic and special cases. An optimized regularization parameter for an MMSE equalizer design is derived and shown to result in appreciable NMSE reduction. 2017 Elsevier GmbH |
