Performance Analysis of a Mesh Satellite System Based on Linear and Continuous Phase Modulations
This paper addresses detailed waveform trade-offs for mesh satellite networks. The waveform analysis is carried out considering spectral efficiency, resilience against non linear distortion, channel impairments and interference for both linear and continuous phase modulation schemes defined in the DVBRCS2 standard. In a mesh satellite architecture two satellite terminals communicate directly through the satellite without accessing the satellite gateway, thus avoiding a double hop link, which is typical for star configurations. Mesh satellite architectures are therefore characterized by a lower transmission latency that enables higher quality of service for delay sensitive applications, e.g., voice communications, teleconferencing, etc.
