TACFIRE Error Control: Improvements Using Iterated Codes.

Abstract

TACFIRE applies a shortened Hamming code to each character of a message. The correction of a single bit error within an encoded character is made by the Hamming decoder. Detectable but not correctable error patterns include all of two and many of four, six, eight, and 10 errors and cause rejection (nonacknowledgement) of the message. On noisy communication channels, retransmissions of rejected messages consume significant resources. To mitigate this high channel usage, a second stage of coding is applied to the characters of the message considered as an information set. This use of Reed-Solomon codes is shown to reduce the rate of message rejection for certain noisy channels. Additional keywords: Tactical communications; Message processing; Iterations. (Author)
