  1. Cramer-Rao lower bound and parameter estimation for multibeam satellite links

    For multibeam satellite links under (full) frequency reuse, interference mitigation techniques are of paramount importance. Before such methods are applicable, however, the most important transmission parameters have to be recovered successfully. The detailed analysis of the related log-likelihood function shows that a beamwise decoupling of the estimation task is possible, if the following three conditions are met: (i) alignment of all frequency offsets; (ii) symbol synchronicity; (iii) orthogonal synchronization sequences.

    This paper presents the design of a digital binary phase shift keying demodulator for application in satellite high-rate carrier telecommand system. The design of all functional modules is shown in details as well as the mathematical analyses concerning the performance evaluation. Test results of a field-programmable gate array implemented prototype are presented and discussed.

    We propose a constant false alarm rate frame detector for satellite-based automatic identification system in the presence of additive white Gaussian noise and frequency offset. False alarm probability and detection probability of the proposed detector, which is based on the periodicity of the training sequence, are analyzed in this paper. Simulation results prove that performance of the proposed detector is superior to that of the frame detector based on cyclic autocorrection when message collisions exist.

  4. Peer-to-peer cooperation for GPS positioning

    Version of Record online: 13 JUL 2016 | DOI: 10.1002/sat.1186

    A peer-to-peer cooperative positioning technique is presented, which is based on the cooperation between two software-defined GPS receivers by means of a wireless LAN connection. Both the outdoor-to-indoor and outdoor-to-outdoor scenarios are considered. For each scenario, we assess the satellite signal acquisition and its computational load and the performance in terms of position accuracy and time-to-first fix of the positioning procedure.

  5. Using SPDY to improve Web 2.0 over satellite links

    This paper evaluates the performance of SPDY, which is a protocol optimized for the access to Web 2.0 contents over fixed and mobile devices, when used both in real and emulated satellite. Results indicate its effectiveness if compared with HTTP, but at the price of a more fragile behavior when in the presence of errors. Nevertheless, our investigation also showcase how SPDY can also reduce the transport overhead experienced by middleboxes typically deployed by service providers using satellite links.
