Error Correction in High Frequency Automatic Link Establishment Radios With and Without Link Protection

Free registration required

Executive Summary

Error correcting techniques used by High Frequency Automatic Link Establishment (HF ALE) radios, including those with link protection, transform a basic 24-bit ALE word into 147 bits to be transmitted and received. This paper examines the effect random errors in the 147 received bits have on the received 24-bit ALE word. High Frequency Automatic Link Establishment (HF ALE) radios conforming to MIL-STD-188-141A utilize error correcting code, interleaving, and redundancy to reduce errors in the received data.
