VHF Air/Ground Communications for Air Traffic Control: A Decision Tree Approach to System Innovations. Volume 1
Abstract
Improvements to VHF air/ground communications for civil aviation in the 118-137 MHz aeronautical mobile frequency band are systematically explored by means of a decision tree approach. Seven individual papers analyze in detail the operational and technical factors involved in making these improvements. Basic tradeoffs between analog and digital modulation are discussed to frame the problem. Near-term improvements utilizing various analog modulations with closer channel spacing are first reviewed. Then far-term improvements employing a wide range of digital modulation and coding techniques are considered. Multiplexing methods - frequency, time, and code division - are discussed in detail. Methods for random access to a shared communications channel are compared, with emphasis upon real-time operations for air traffic control. Volume I provides an executive summary of this work, while Volume II presents the technical details.. ..
