      Protograph based non-binary low-density parity-check codes outperform their binary competitors by far. Sophisticated code designs allow performances close to theoretical bounds, such as the random coding bound (RCB). An efficient frequency domain implementation of the algorithm guarantees a manageable decoding complexity even for moderate Galois field (GF) orders.

      This paper describes an innovative receiver architecture for the satellite-based automatic identification system. The receiver performance has been fully validated in the presence of the typical satellite channel characteristics. In particular, it is shown that the devised receiver provides an excellent performance against the noise, as well as a large resilience against message collisions, Doppler shift, and delay spread.

    2. Improving the spectral efficiency of FDM-CPM systems through packing and multiuser processing (pages 64–75)

      We consider a frequency division multiplexed system where each user employs a continuous phase modulation and iterative detection/decoding. We show that, by taking into account the increased interference using properly designed multiuser detection and synchronization schemes, it is possible to implement transmission schemes with unprecedented spectral efficiency at a price of a limited complexity increase with respect to a classical single-user receiver which neglects the interference.

    3. Practical MIMO aspects in dual polarization per beam mobile satellite broadcasting (pages 76–87)

      Pantelis-Daniel Arapoglou, Paolo Burzigotti, Ana Bolea Alamañac and Riccardo De Gaudenzi

      Building upon recent studies promoting the use of MIMO over dual polarization per beam Mobile Satellite Broadcasting systems, the present paper analyzes various system parameters including how time interleaving, terminal antenna cross-polarization discrimination and intrasytem interference impact MIMO performance. A MIMO channel estimation approach compatible with the latest DVB-SH standard is introduced and the impact of non-linear distortion on the most prominent space-time coding alternatives is investigated.

    4. GSSTP: a signalling transport protocol for DVB-S2 GSE-only transmission systems (pages 88–97)

      This paper presents a new extensible lightweight Generic Stream Signalling Transport Protocol for Digital Video Broadcasting systems. The method can be used to realise an all-IP transmission system that directly uses the Generic Stream Encapsulation. It supports a range of table formats, including tables using the extensible markup language, extensions to support security and compression and transmission of MPEG-2 encoded tables to provide backwards compatibility with legacy systems using the MPEG-2 transport stream.
