STUDY AND APPLICATION OF ADAPTIVE COMMUNICATION TECHNIQUES IN THE DEFENSE COMMUNICATION SYSTEM.
Abstract
This report concerns adaptive techniques for use in submarine cable, HF, and land-line digital links of the DCS for the period 1970-1975. The overall objective is to devise adaptive data systems which maintain a desired quality of transmission in terms of bit-error-rate under variable conditions of transmission at given, fixed input bit-rates and is directed to adaptive control of the data channel in distinction to control of the data source. The report covers the HF phase of study and work on adaptive anti-distortion systems. Related studies are presented on error-rate in the presence of distortion and noise, pulse response of an FDM stage, and extrapolation of channel frequency response from measurements over a finite band.
