ERROR CONTROL FOR DIGITAL COMMUNICATIONS IN THE TACTICAL ENVIRONMENT
Abstract
This paper considers error detection with retransmission and forward error correction for the transmission media used in the tactical environment: i.e., troposcatter and high frequency radio. The results of extensive error pattern measurements in these two media are reported. In the troposcatter channel, bursts with error densities up to 50% and lasting several seconds, followed by several minutes of error-free transmission, are not uncommon. In HF channels, bursts of similar length with short error-free intervals are frequently found; the error density is only 5%. A practical approach used in the design of coding systems (which prevent information degradation) incorporates channel testing. The error patterns that are collected are used in simulation of various coding techniques, with the objective of identifying the most promising.
