In this paper, we analyze the capability of satellite broadcasting systems to offer different levels of quality of service (QoS). We focus on the European telecommunications standards institute satellite digital radio and digital video broadcasting s

In this paper, we evaluate a multilevel coding (MLC) scheme with multistage decoding (MSD) designed for satellite broadcasting communications. The impact of three different satellite system impairments on the decoding performance is analyzed. First,

In order to reduce the computational complexity of maximum-likelihood symbol estimation (MLSE) demapping of multilevel codes which is based on block partitioning and which produces soft input for a multistage decoding (MSD) process, three different d

This chapter assesses the choice of the physical layer parameters (code rate, modulation, time interleaving) that are best suited for satellite broadcast. The optimum choice depends on the system’s envisaged spectral efficiency or available signal-

We introduce the use of multidimensional (MD) constellations in a multilevel coding (MLC) scheme with multi-stage decoding (MSD) designed for broadcasting communications, where services with different quality of service (QoS) are desirable. We show t

We propose and analyze two strategies to provide different levels of quality of service (QoS) to the DVB-SH standard. An extension of the interleaving scheme is investigated to support low latency service requirements for interactive services based o

This paper assesses the spectral efficiencies that can be achieved in theory and simulation for several channel models, and where the same spectral efficiencies can result from different combinations of the signal constellation and channel code rate.

In this paper, we propose a multilevel coding (MLC) scheme suitable for satellite communications, where different QoS levels are required. We introduce a novel characterization of schemes based on mutual information, called multi-stage decoder (MSD)
