AMR DIGITAL TROPOSCATTER TEST RESULTS

Abstract

The report describes the performance of three types of contractor furnished digital modulation equipment, using simultaneous data from an FM-FDM system as a standard. The tests covering a period from November 1964 through May 1965 were conducted on an over-water path between East Island, Puerto Rico and Grand Turk Island, BWI. The standard FM-FDM system technique referenced was the Radio Set AN/MRC-98, a transportable tropospheric scatter radio set operating in the 755-985 MHz range, with an output r.f. power capability of 10 KW. The digital techniques were variations of Pulse Code Modulation, Pulse Position Modulation, and Delta Modulation schemes. A description of test instrumentation configurations and data collection procedures is presented. Test results are discussed and presented in tabular and graphical form.
