This paper addresses the effect of the phase noise on filter bank modulation systems. We compare the Discrete Multitone (DMT) with the Filtered Multitone (FMT) systems developing an analysis of the distortion due to the Common Phase Error (CPE), the Inter Symbol Interference (ISI) and the Inter Channel Interference (ICI). We consider the non-coherent (NCR) and the coherent receiver (CR) where the NCR estimates the data symbols without the knowledge of the CPE while the CR assumes perfect knowledge of the CPE.
