Abstract

Digital messages may contain bit errors when sent over a radio channel. Error correcting codes generally provide some measure of error correction. As an exam- ple, take a (32,21) code composed of a BCH (31,21) code plus one additional check sum bit. This particular code detects up to 3 bit errors per word, can correct up to two errors, and has a code distance of 6. In decoding and error correcting, falsing to the wrong decoded characters is a possibility.
