Capacity Enhanced High Throughput Satellite - Coded-Beams resource management strategy

Abstract

the manuscript investigates the capacity enhancement derived from the new trend of Coded-Beam High Throughput Satellite (CB-HTS) System; CB-HTS is a methodology of adoption of Direct- Sequence Code Division Multiplexing (DS-CDM) orthogonal coding as a resource allocation associated with each beam of multi-beam satellites. This system offers no spectrum reuses and there is no co-channel interference between beams as they are isolated with the code orthogonally, therefore the system throughput increases without scarifying any resources or increasing neither system complexity nor latency. The presented work uses the affordable polarization resource at the user terminal side to increase the capacity in each beam by using both vertical and horizontal polarization support with the conventional multiple accessing techniques between users in the beam. Results show the superiority of proposed scheme compared to current state of- the art in cases of practical interest.
