Impact of phase noise on the performance of OFDM systems over frequency selective channels

This paper deals with the problem of modelling of phase noise in OFDM systems, and the impact it may have on the symbol error rate performance of such systems subject to a number of system variables and a number of additive white Gaussian noise channel conditions which may be encountered when such systems are deployed for certain applications such as high speed wireless LANs and digital television terrestrial broadcasting (DTTB). The source of the phase noise process which is the transmitter and receiver local oscillators are modelled using what is believed to be commercially realizable phase noise masks. Such masks represent the long-time averaged power spectral densities of the local oscillator output signal
