A Dynamic Bandwidth Allocation Scheme for a Multi-spot-beam Satellite System

Abstract

A multi‐spot‐beam satellite is an attractive technique for future satellite communications since it can support high data rates by projecting high power density to each spot beam and can reuse a frequency in different cells to increase the total system capacity. In this letter, we propose a resource management technique adjusting the bandwidth of each beam to minimize the difference between the traffic demand and allocated capacity. This represents a reasonable solution for dynamic bandwidth allocation, considering a trade‐off between the maximum total capacity and fairness among the spot beams with different traffic demands.

Ka-band flexible power multibeam antenna

“…There have been tremendous demands of geosynchronous earth orbit (GEO) satellite antenna systems to provide multiple spot beams for various communications or broadcasting services [1]. In accordance with this trend, we developed a Kaband communication payload of the Chunrian satellite launched in 2010 [2].…”

Design of Ka band reconfigurable beam antenna using genetic algorithm

“…Due to increasing demands of broadband broadcasting and communication traffic, flexible satellite systems are widely studied with reconfigurable beam antennas [1]- [3], adaptive bandwidth allocation schemes [4] and high performance multiport amplifiers [5] for multibeam antennas. Especially 21-GHz-band antenna which can provide new broadcasting services such as ultrahigh-definition TV and 3D TV based on broadband characteristics is drawing interest.…”

A new satellite communication bandwidth allocation combined services model and network performance optimization

“…However, isolated link connection still took up more control bandwidth. Park Unhee proposed a dynamic bandwidth allocation scheme for a multi-spot-beam satellite system [6]. The weighting coefficients were set to balance traffic and idle bandwidth, which adjusted bandwidth allocation automatically.…”
