Outage Performance for the Cognitive Broadband Satellite System and Terrestrial Cellular Network in Millimeter Wave Scenario

This paper investigates the outage performance of cognitive broadband satellite systems and terrestrial cellular network in millimeter wave (mmWave) scenario. Considering the state-of-art standard recommendations and mmWave propagation model, we first define a general framework for the coexistence of broadband satellite system and terrestrial cellular networks with distinct geometry, configuration, and channel characteristics. Then, by employing a interference temperature constraint at the fixed satellite service (FSS) receiver to limit the interference below an acceptable level, closed-form expression for the outage probability (OP) of the cognitive cellular user is derived, which is general and applicable to various channel parameters and geometric scenarios. Eventually, simulation results are carried out to verify the theoretical derivations, and shows the impact of key system parameters on the performance of the terrestrial cellular user with the coexistence of FSS.
