Abstract :
In this paper we investigate the effect of phase noise on coded OFDM transmission with parameters typical for present OFDM based WLAN standards. Two different scenarios are compared, namely when the local oscillator at the receiver is realized as a free running oscillator or as a PLL. System performance is evaluated as degradation of the effective SINR, using BER simulations and in terms of achievable cut-off rate for different M-QAM OFDM schemes in the presence of the phase noise.
