“…The return link demodulator is designed and developed to operate the low SNR because of mobile environment. Real-time processing protocol also is developed to support Quality of Service (QoS) [4][5][6]. The dynamic resource management scheme is adopted for the system efficient allocation of frequency and time slots.…”

“…The system is implemented the solution of a resource allocation problem with heterogeneous resources (coding rates, modulation types and frequency bandwidths) and heterogeneous subscribers (home users, enterprise users, satellite news gathering users) in order to achieve a high utilization of radio resources while providing a stable link quality. A non-linear integer programming approach for the resource allocation problem and an efficient heuristic solution algorithm are implemented in the system [4][5][6].…”

SUMMARYIt is difficult to implement the broadband satellite Internet and broadcasting service for mobile environment. The paper presents the design and implementation of a mobile broadband satellite access system. In case of the system design, mobile terminal service is considered a critical factor than fixed terminal services, such as resource management, antenna tracking, weak signal recovery. In the paper, mobile broadband interactive satellite access technology system (MoBISAT) is presented. The system network, which is composed of a star network, consists of time division multiplexing-based forward link and multi-frequency time division multiple access-based return link. The MoBISAT provides both Ku-band satellite TV and Ka-band high-speed Internet base on DVB-S/DVB-RCS standards to the passengers and crews for land, maritime and air vehicles. The key factors of hub and mobile terminal are addressed for the design and implementation of the MoBISAT. Especially, the design and implementation of the return link demodulation method, resource management scheme and mobile terminal structure including mobile antenna are described.

“…Based on these two policies, different resource optimization algorithm should be applied. Currently, we found that most optimization algorithms are based on the assumption that all data to be sent already exists in the DVB radio station server( [3], [5], [6]), which means they all follow policy 1, and no algorithm considering the characteristics of the coming Internet data streams is found yet. Hence, the current existing algorithms may not be fit for more real-time demanding services which prefer policy 2 in BNCC and they won't be able to fully exploit the BNCC resources.…”

Digital Terrestrial Video Broadcasting (DVB-T) provides an ideal means for providing services with both high data rate and high mobility, which exceeds the ability of current access technologies like UMTS, WLAN, and so forth. Combined with other media as a return channel for user requests and acknowledgement signaling, DVB-T can provide interactive data services. In this paper, the integrated Internet and DVB-T network is proposed to provide broadband Internet access services for users with high mobility. In order to make effective use of valuable DVB-T resources, we present a bandwidth allocation algorithm SOBAM(Satisfaction Oriented Bandwidth Allocation Method), which is based on a new concept: user satisfaction. The simulation results powerfully show that SOBAM gives good QoS differentiation and make plentiful utilization of DVB-T available bandwidth. With SOBAM, the integrated Internet and DVB-T network can provide a soft system capacity which is similar to the one in CDMA networks.Keyword: DVB-T, integrated network, satisfaction, resource management Abstract-Digital Terrestrial Video Broadcasting (DVB-T) provides an ideal means for providing services with both high data rate and high mobility, which exceeds the ability of current existing access technologies like UMTS, WLAN, and so forth.

“…However, in those papers the objective was to optimize the time-slot assignment over an already determined frame structure, whereas the objective of this paper is to optimize the frame structure itself. In [7], the radio resource allocation problem in presence of heterogeneous resources and heterogeneous subscribers for digital video broadcast-return channel via satellite (DVB-RCS) systems has been studied as a Timeslot Assignment Problem (TAP) and formulated, as a consequence, as a Nonlinear Integer Programming (NLIP) problem where the integer variables are decision variables indicating the timeslot assignment to given service classes. The problem of bandwidth efficiency has been discussed also in [8], where the efficiency of different scheduling policies is investigated and the optimization of bandwidth segmentation is solved by formulating and solving a Knapsack problem, i.e.…”

In current generation of satellite networks, modulation and coding schemes can be dynamically changed in real-time to face different link conditions. Therefore, the link budget is no more required to be computed under the worst-case, with relevant advantages in terms of efficiency. The new DVB-RCS2 standard extends the dynamic modulation and coding to the return link: by using different modulation and coding schemes within the uplink frame, the terminals experiencing good link conditions transmit at very high bitrates, while the terminals experiencing fade events transmit at lower bitrates. This paper addresses the problem of optimizing the uplink frame modulation and coding schemes based on the current link conditions experienced by the terminals and on their transmission capacity requirements. The problem is formulated as an Integer Program and an efficient Linear Program approximation is proposed. Simulation results validate the proposed approach
