International Journal of Satellite Communications and Networking

International Journal of Satellite Communications and Networking aims to provide a quality technical journal for the academic and professional engineer covering all aspects of satellite systems, networks, components and services. The journal focuses on new research results as well systems operation, trials and descriptions and service provision. The goal is to provide a blend of systems oriented and general research papers.

  1. New formulation of GNSS acquisition with CFAR detection

    Article first published online: 10 FEB 2016 | DOI: 10.1002/sat.1177

    This paper deals with the analysis of the acquisition process performed by a global navigation satellite system receiver with a pilot and data channel or in case of global navigation satellite system hybrid receiver. To realize this operation, firstly, we introduce a cell- averaging-constant false alarm rate (CFAR) then secondly a data-pilot cell-averaging-CFAR detector fusion based. In the two cases, we derive a closed-form analytic expression for the probabilities of detection and false alarm, which are validated by Monte Carlo simulations.

  2. Architectures for next generation high throughput satellite systems

    Article first published online: 27 JAN 2016 | DOI: 10.1002/sat.1175

    This paper presents a model to estimate aggregate system capacity as a function of radio band, available spectrum, spot beams, waveforms, and payload capability comprising antenna size, power, and digital/analog connectivity across various links and availability objectives for next-generation high throughput satellite systems. This paper presents architectural building blocks for next-generation high throughput satellite systems using low earth, medium earth, and geosynchronous orbit satellite constellations, with and without onboard processing and inter-satellite links. This paper describes a system implementation approach using industry standards such as DVB-S2X and 4G LTE.

  3. Eutelsat HTS systems

    H. Fenech, A. Tomatis, S. Amos, V. Soumpholphakdy and J. L. Serrano Merino

    Article first published online: 26 JAN 2016 | DOI: 10.1002/sat.1171

    HTS systems are a breakthrough in satellite communications because they offer a considerable reduction in the service cost. This brings satellite communications closer to the consumer with costs and quality of service comparable with terrestrial services and on a ubiquitous basis.

  4. A novel routing design in the IP-based GEO/LEO hybrid satellite networks

    Zhaofeng Wu, Guyu Hu, Fenglin Jin, Yu Song, Yinjin Fu and Guiqiang Ni

    Article first published online: 13 JAN 2016 | DOI: 10.1002/sat.1174

    Based on the division of the Earth surface, the geostationary orbit/low earth orbit hybrid satellite network is able to achieve the separation of the user layer and the satellite segment along with the separation of the user identifier and locator, which greatly facilitates the user mobility management in the satellite networks. The proposed hop-constrained adaptive routing mechanism can then be applied to realize the load balancing in the low earth orbit satellite segment.

  5. A modified normalized min-sum algorithm for LDPC decoding using order statistics

    Wen Xue, Tian Ban and Jianxin Wang

    Article first published online: 11 JAN 2016 | DOI: 10.1002/sat.1173

    Thumbnail image of graphical abstract

    We propose a new modified normalized min-sum algorithm (NMSA) for low-density parity-check codes decoding. Two different modification factors are used to normalize the results of check node renew calculations. Simulation results show that the new modified NMSA achieves better bit error rate performance than NMSA without adding implementation complexity.
