Simple Decoders and Correlators for Cyclic Error-Correcting Codes

Several promising techniques for instrumenting error-correcting codes are briefly described. These techniques consist of digital decoders for the binary symmetric channel and for the binary erasure channel, and analog word correlators for variable and low bit-rate operation. The performance pay-off of these techniques in comparison to their implementation simplicity indicates the possibility of incorporating them into certain types of communication systems with advantageous results.
