CSEL Interface Update: K-Band Microprocessor Demonstration.

Abstract

The objective of this demonstration/study is to provide the Air Force with basic data and techniques for expanding the capabilities of the K-Band Terminal Simulator. The current simulator consists of three communication channels, each with several real-time effects (Doppler shift, frequency hop, signal fading, and MFSK) driven by a minicomputer which updates all of these real-time effects every 5 milliseconds. Expansion of the K-Band Terminal Simulator along present lines would increase the burden on the minicomputer and therefore increase the basic 5 millisecond time step, which may already be too long for some applications. The results of this study show that an alternative, vastly superior approach to expansion of the simulator would be to use a separate microprocessor to drive each individual channel. This would relieve the main minicomputer of the fast real-time chores and leave it with only non-time critical system control, operator interface, and housekeeping tasks. This approach would give almost unlimited expansion capability and would allow reducing the basic time step somewhat. Complete results, along with all hardware and software documentation are contained in this final report.
