Abstract :
This paper analyzes the effects of phase noise in multi-user OFDM systems. The impact on system performance of different phase noise characteristics and received power among users is considered. The main conclusion that can be achieved is the importance of power control in order to avoid a near-fact effect. Besides, the presence of transceivers with bad phase noise characteristics can ruin the performance of better (more expensive) ones.
