HF Modem Feasibility Demonstration
Daniel D. McRae, Ronald S. Lefever, Joseph N. York · 1982
The objective of this program was to evaluate a recently developed, bandwidth efficient, channel-adaptive digital modem for radio communications below 30 MHz (High Frequency (HF)). The block and bit error performance during simplex operation was characterized over both Harris Corporation and RADC's HF simulators. Performance for 2.4, 3.6, and 4.8 kb/s in a 3 kHz channel was obtained on both HF simulators while performance at 8 and 16 kbps in a 6 kHz channel was obtained only on Harris HF simulator. (Author)
