About QoS in DVB-S2/RCS Systems

The standardization of a Return Channel via Satellite and the satellite community efforts in term of interoperability over the last few years stands for major milestones in the development of reliable, efficient and low cost satellite equipments. It leads to quite a positive outcome: geostationary satellite networks are expected to play a decisive role in bridging the existing digital divide th...

TCP behavior in a DVB-RCS environment

In 2000, ETSI has approved and published a standard for interactive broadband satellite services (DVB-RCS) . One of the most important features of this standard is the implementation of DAMA strategies aiming at a fair and efficient use of the shared resources in the satellite return channel. A DAMA scheme introduces a new control loop, based on a signaling exchange between STs and the NCC, ins...

Resource Allocation in DVB-RCS Satellite Systems

This paper compares several approaches for dynamic allocation in geo-stationary networks based on DVB-RCS system. Each Satellite Terminal (ST) regularly sends requests to the Network Control Center (NCC) which in turn allocates resource to the users. Unfortunately, this delayed request-assignment makes the dynamic bandwidth allocation very difficult. Simple mechanisms such as a fixed allocation...

The Turbo Code Standard for DVB-RCS

Convolutional turbo codes are very flexible codes, easily adaptable to a large range of data block sizes and coding rates. This is the main reason for their being adopted in the DVB standard for Return Channel via Satellite (DVB-RCS). The paper presents the turbo coding/decoding scheme specified in this standard, for twelve block sizes and seven coding rates. Simulation results show the perform...
