Unified Multibeam Satellite System Model for Payload Performance Analysis

This paper presents a novel unified multibeam satellite system model for the performance analysis of different satellite payloads. The model allows the analysis in terms of Signal to Interference plus Noise Ratio (SINR) and CoChannel Interference (CCI). Specifically we formulate the SINR as a function of the multibeam geometry for a given user location granularity. Furthermore, we apply our mod...

Multi-beam Satellite Resource Allocation Optimization for Beam Hopping Transmission

Multi-beam satellite systems have been studied a lot in the last ten years. They have many promising features like power gain, interference reduction, high flexibility to adapt the asymmetric traffic distribution, and the improvement of the system capacity compared with single-beam systems. In multi-beam satellite systems, the beamforming antenna can generate a number of spot beams over the cov...

Performance Analysis of Integrated Wireless Sensor and Multibeam Satellite Networks Under Terrestrial Interference

This paper investigates the performance of integrated wireless sensor and multibeam satellite networks (IWSMSNs) under terrestrial interference. The IWSMSNs constitute sensor nodes (SNs), satellite sinks (SSs), multibeam satellite and remote monitoring hosts (RMHs). The multibeam satellite covers multiple beams and multiple SSs in each beam. The SSs can be directly used as SNs to transmit sensi...

Coordinated Multibeam Satellite Co-location: The Dual Satellite Paradigm

In the present article, a new system architecture for the next generation of satellite communication (SatComs) is presented. The key concept lies in the collaboration between multibeam satellites that share one orbital position. Multi-satellite constellations in unique orbital slots offer gradual deployment to cover unpredictable traffic patterns and redundancy to hardware failure advantages. T...
