Adaptive Radio Resource Allocation for a Mobile Packet Service in Multibeam Satellite Systems

Abstract: In this paper, we introduce an adaptive radio resource allocation for IP‐based mobile satellite services. We also present a synchronous multibeam CDMA satellite system using an orthogonal resource sharing mechanism among downlink beams for the adaptive packet transmission. The simulation results, using a Ka‐band mobile satellite channel and various packet scheduling schemes, show that the proposed system and resource allocation scheme improves the beam throughput by more than two times over conventional system… Show more

“…Nevertheless, this piecewise block phase recovery algorithm hardly requires additional complexity compared to a conventional one. The main computational load in the phase recovery is estimating the phase using (2), and compensating the phase using (1). In this sense, the computational loads of the conventional and proposed algorithms are the same.…”

“…The beyond 3G (B3G) system has been developed to fully integrate various networks including satellite systems [2] by targeting mobiles with a high speed of up to 300 km/h. For example, the 3rd Generation Partnership Project standards are now targeted to support a maximum user speed of 200 km/h [3], while the IEEE 802.16e standard is targeted to support a user speed of 60 km/h and will be extended to a maximum 250 km/h [4].…”

“…In order to use both benefits of using satellite network and terrestrial network, a device which can use both networks is needed. To provide high speed satellite multimedia service through personal mobile devices, current satellite transponder, which uses single beam method, needs to be replaced with new transponder with higher frequency efficiency, smaller size and which can provide broadcast multi-beam, to improve its' performance [4]. However, the research shows that co-channel interference on a device will be a critical issue and will eventually causes big problem.…”

“…Our previous studies discussed the adaptive usage of advanced modulation and coding schemes for future mobile satellite systems [7][8][9]. We proposed an adaptive radio resource allocation scheme for mobile packet services in a synchronous multibeam satellite system by considering the physical-MAC layer interaction, and showed various interesting results including the effectiveness of a system-level adaptation [7].…”
