A building concept of a promising meteor-burst communication system

Subject and Purpose. The paper presents a building concept of a promising meteor-burst communication system with enhanced bandwidth, noise immunity and covert operation of the system. Methods and Methodology. The proposed methods and technical solutions include selection of meteor-burst communication network topologies and employment of code division multiplexing and software-controlled intelligent antennas (SMART antennas) with adaptive techniques in view of varying operating conditions. Results. A meteor-burst communication network has been proposed in several topology variants providing a means of a simultaneous assess of subscriber stations to several base stations of the network, with both subscriber and base stations employing SMART antennas. It has been shown that the software-controlled pointing of these antennas should take into account seasonal changes in the radiant density of the sporadic meteor complex, implying that the radiation pattern maxima should be placed in the most probability areas of the appropriate meteor tracks, with pattern nulls located on the interference source directions. Signals with direct sequence spread spectrum have proved themselves well against interference fading. For these signals, digital processing techniques have been suggested. Conclusion. It has been shown that the proposed concept of enhanced bandwidth, noise immunity and covert operation of the meteor-burst communication system, as well as its subsequent refinement, is expedient to implement through the use of Software Defined Radio, SDR.
