ERROR CONTROL THROUGH CODING. VOLUME I. SUMMARY OF RESULTS.
Abstract
The research was primarily devoted to the application of error control techniques. This discipline has developed a body of knowledge that can be extremely valuable to communication systems designers if criteria for the use of error control coding can be developed. The work included an analysis of channel statistics that leads to a computer program designed to choose an optimum error control technique from standard channel statistics and data transmission parameters. Variable length, variable redundancy codes and their applications were studied. Comparisons of block and recurrent codes were made; in addition a study was made of error propagation in recurrent codes. A cyclic decoding procedure for the familiar Bose-ChaudhuriHocquenghem code was developed. Comparisons were made between forward error correction codes and error detection codes with feedback and retransmission, with data throughput rate the criterion for comparison. Finally, a technique for combining error detection with message synchronization is described. (Author)
