Satellite communication is one of the key technologies that is enabling next-generation networks. However, nearest-satellite-supported downlink transmission may not meet a user's requirements due to limited signal strength, especially in emergent scenarios. In this paper, we investigate a coordinated multi-satellite joint transmission system from a system-level perspective, where a user can be served by multiple satellites to improve its quality-of-service (QoS). Furthermore, we analyze the coverage and rate of a typical user in the joint transmission system. Simulation and numerical results show that the introduced system achieves a higher coverage probability than the traditional nearest-satellite-supported network. Moreover, a user's ergodic rate can be maximized by selecting an appropriate number of serving satellites.
