This paper proposes a pilot subcarrier allocation approach for OFDM waveforms, which enables construction of phase-noise estimate with high efficiency and low overhead in non-iterative manner. The complexity and the performance of the overall phase-noise suppression algorithm together with the proposed pilot allocation approach are evaluated against a reference algorithm. The performance simulations are carried out in SU-MIMO and MU-MIMO 5G-like radio links at 28 GHz carrier frequency.
