This paper addresses the problem of phase noise mitigation in communications links utilizing DFT-S-OFDM waveforms. The paper discusses use of two different pilot configurations to do the compensation of the common phase error part of the phase noise. The pilot configurations are inserting pilots as logical symbols before the DFT spreading and inserting frequency domain pilots as subcarriers as in OFDM waveforms. Then, based on the former pilot configuration, a computationally efficient intercarrier interference compensation algorithm is proposed. The pilot configurations and techniques are evaluated in terms of peak-to-average power ratio and phase noise mitigation performance with realistic numerology in numerical simulations.
