Abstract:
A method for encoding and decoding a binary encoded text message using context-based error detection and correction, comprising the steps of:defining a dictionary of m dictionary words, W.sub.i, where each dictionary word is assigned a unique binary code word, represented by a series of bits, and an identifier, IDFR.sub.i such that for any two words W.sub.p and W.sub.q from said dictionary, if IDFR.sub.p =IDFR.sub.q, then said binary code word for said word W.sub.p differs from said binary code word for said word W.sub.q by more than one bit, and where i, p, and q are each an index from 1 to (m-1), and m is a positive integer;receiving a message comprised of words selected from said dictionary;encoding said message to form an encoded message comprised of selected ones of said dictionary words;transmitting said encoded message;receiving said encoded message;decoding said encoded message to form a decoded message comprised of decoded message words;displaying said decoded message words; anddisplaying candidate words from said dictionary having code words one bit different from said code words associated with suspected erroneous words selected from said decoded message words if said decoded message includes any suspected erroneous words.
