LINK EVALUATION AND TAPE MERGING COMPUTER PROGRAMS

摘要

This report is one of a series that describes a computer program designed to predict the performance of communication networks using HF. ionospheric scatter, and tropospheric scatter propagation modes.nThe present report outlines the models and procedures used to write a computer routine to convert signal-to-noise-ratio predictions into a teletype character error rate for a channel and to estimate the usable number of teletype channels the circuit can support. This conversion considers such circuit parameters as teletype speed, teletype code, diversity reception, modulation, and detection techniques.
