Abstract

The topic of this paper is low-complexity yet high-precision phase-noise mitigation in a realistic cm-wave radio link. The proposed algorithm for phase-noise induced intercarrier interference mitigation works in time domain. We propose a filtering solution that is computationally very simple to implement on silicon. Noise from initial phase-noise estimate is removed with cumulative sum filtering instead of a very high order complex-tap filter. The performance of the proposed algorithm is evaluated in realistic ITU-R Urban Microcell Non-Line-of-Sight channel as well as in white Gaussian noise channel, and with state-of-the-art phase-locked-loop oscillator generated phase noise. The obtained results show that highly-efficient phase-noise mitigation can be obtained using the proposed approach. For the example 5G case, the algorithm suppresses the phase noise so that the bit-error-rate performance is near the case without phase noise.
