Abstract : This report describes the results of a study to define a baseline advanced Meteor-Burst Communication (MBC) system that can serve as a step along the way to developing new Federal Standards for a system of this type. Five technology areas have been evaluated in this study: advanced modulations, including error-correcting codes; adaptive data rates; adaptive antennas; network topology and routing; and mobile systems. The recommended modulation for advanced NBC systems in adaptive trellis-coded modulation (TCM) using M-ary PSK with convolutional coding for error correction. The recommended antennas are adaptive in beam forming, nulling, and polarization. For MBC systems that consist of multiple sites, modern networking techniques are recommended, including adaptive routing capabilities. Finally, a program plan is suggested for establishing a baseline version of an MBC system with these advanced technologies. This baseline system must be tested to demonstrate the feasibility of the concepts and to gather performance data that can help define the new Federal standards that will permit the orderly development of the next generation of MBC systems.
