May 1981 | NTIA Technical Report TR-81-74
Joseph E. Farrow; Larry G. Hause
Abstract: This report is the sum of a three–part effort by the Institute for Telecommunication Sciences (ITS) to provide technical recommendations for the DCS Long–Haul Tactical Common system, subsystem, and equipment technical standards for digital radio. The work was sponsored by the Defense Communications Engineering Center, Reston, VA. Primary recommendations for the system standards include suggested reference circuit and channel distances within a common overseas DCS terrestrial segment; the suggestion that only digital subsystems be included in the global reference circuit; and the statement that only parameters directly measurable in digital systems (such as bit-error-rate) be used in defining performance. The main recommendations for subsystems standards include a recommended scope for subsystem standards; suggestions for specific content in which appropriate standards and subsystem parameters are identified; and exclusion of all reference to FDM/FM parameters from new drafts. Some important guidelines for the equipment standards include an outline for the equipment standards; recommendations on the realism and practicality of design parameters; and recommendations on possible techniques to be included in the standard for upgrading existing facilities.
