ADAPTIVE TECHNIQUES FOR LONG RANGE TRANSMISSION OF PULSE CODE MODULATION TELEMETRY DATA

Abstract

A study and development program is described involving the application of certain techniques for long range transmission of PCM telemetry data. The objective of the program was to explore and develop those areas of CM system design which most satisfactorily meet long range transmission and data handling requirements. The technical approach includes optimization of system information capacity, selection of an optimum R. F. link, and investigations of format compromises, to a tain the maximum information rate possible over a wi e range of transmission path lengths, and a variety of da a requirements. The type of modulation (phase) for the R. F. link is shown by theoretical analysis to be superior to any other. A system desi n and engineering model development program has been completed. Results of test performed on the model verify the feasibility of the engineering design. (Author)
