Title:
COMPARATIVE PERFORMANCE EVALUATION OF DIGITAL DATA MODEMS FOR HF RADIO
Corporate Author:

Abstract:
The comparative performance of several digital data modems over a high-frequency HF radio link is described in this document. During April and June 1964, field testing of evaluation models of new phase-shift keyed PSK modems was conducted over a leased 6900-nautical mile HF radio circuit from Pretoria, South Africa, to Riverhead, New York. The superior bandwidth economy of PSK over frequency-shift keyed FSK modulation was demonstrated. This work was accomplished as part of the ESD program to improve missile test range HF digital data transmission.
