MILCOM '84 - Military Communications Conference, Los Angeles, CA, October 21-24, 1984, Conference Record. Volume 3

Questions of orbital congestion and frequency planning are investigated, taking into account an overview regarding the techniques for the analysis of spectral and orbital congestion in space systems, the DOD space systems data base, interference problems for nongeostationary satellites, the spectrum/orbit utilization program for geostationary satellites, and the threat of space debris. Other studies reported are related to modulation analysis, narrowband rejection techniques, the government use of commercial telecommunications, multiple access techniques, voice and data transmission, adaptive A/D converters for interference reduction, and terminal costs, impacts, and drivers. Attention is given to a methodology for choosing between alternative communications systems, risk analysis and satellite communications terminals, diversity combining for frequency-hop spread-spectrum communications with partial-band interference, governments need and commercial contributions in the area of telecommunications, and subjective performance of selected speech coders in the presence of channel errors.
