Impact of phase noise on the performance of OFDM systems

This paper deals with the modeling of phase noise in Orthogonal Frequency Division Multiplexing (OFDM) systems. and the impact it may have on symbol error rate (SER) performance. The SER is subject to a number of system parameters and channel conditions which may be encountered in applications such as high speed wireless LANs and Digital Television Terrestrial Broadcasting (DTTB). The sources of the phase noise ate the transmitter and receiver local oscillators. They are modeled using what is believed to be commercially realizable phase noise masks. Such masks represent the long-lime averaged power spectral densities of the local oscillator output signal.
