N2 - Utilization of millimeter-wave bands by next generation mobile networks is expected to make extremely high data rates realizable. However, at such high frequencies, phase noise (PHN) can significantly affect the performance of the communication system. Filter Bank Multi-Carrier systems with Offset Quadrature Amplitude Modulation (FBMC-OQAM) have received increased attention in recent years, but the impact of PHN on them has not yet been extensively studied. In this work, we derive analytic expressions for the interference power, under perfect Common Phase Error (CPE) correction of the OQAM symbols. Numerical evaluation of these expressions shows that FBMC-OQAM is more robust against PHN than Orthogonal Frequency Division Multiplexing with Cyclic Prefix (CP-OFDM). A pilot-based and a pilot-free method are investigated for compensation of the CPE. The latter exploits the structure of the interference in FBMC-OQAM systems. Our numerical results corroborate the efficiency of the algorithm, making FBMC-OQAM an attractive option, as high performance is achievable with no loss in spectral efficiency.
