Ultra high-throughput satellite (UHTS) systems are expected to play an essential role in future beyond 5G and 6G networks. One of the main sources of degradation in such system is the phase noise. Satellite manufacturers and equipment suppliers have to resort to cumbersome and time-consuming transmission chain simulations to estimate the carrier-to-interference ratio (CIR) caused by the phase noise. Therefore, a novel mathematical CIR formula is proposed in this work for the characterization of phase noise in future UHTS systems. Not only does this expression enable an efficient and accurate assessment of the phase noise degradation, but it can be easily incorporated in the satellite link budget and simply requires a predefined phase noise mask as an input. In this context, the influence of the main phase noise variables and the behavior of typical phase noise masks are analyzed, thus, bringing valuable insights. Finally, the theoretical results are validated through numerical simulations.    «
