Application ID: 06465742

Base Claim:
1. A system for transmitting messages over a message channel comprising: a transmitting station including: means for generating a message as a succession of a mutually identical multibit code words which utilizes a small portion of said message channel; said code words including at least one word dedicated to a particular receiving station and having a minimum Hamming-distance of at least two with respect to the remaining code words inclusive of a cyclical transposition of the latter; and a receiving station including: (a) separation means connected to said message channel for extracting a message therefrom; (b) a decoder connected to said separation means for decoding said message, said decoder having a decision means for windowless detection of any word equal in length to at least one of said multibit code words and for indicating at least one code word.

Claim 2:
2. A system as claimed in claim 1 wherein said at least one code word has a minimum Hamming distance in the bit space of at least three bits with respect to any other permissible code word, including the latter's cyclic transpositions, the decision means being capable of correcting at least one bit error in a separated n-bit word.
