Beamforming and Transceiver Optimization with Phase Noise for mmWave and THz Bands

This paper investigates the impact of phase noise on the transceiver signal processing originating from the local oscillators (LOs). We explore the impact of these effects with different transceiver architectures, illustrate the beam shape properties, and quantify their impact on the system performance for different modulation schemes in terms of error rates. Specifically, we model the phase noise both as Wiener and Gaussian distributed with covariance structure depending on the architecture used to share the LO signals.
