Final Report on Hobbs' Failsafe Decoder.
Abstract
To improve the reliability of digital communications systems, an encoder/decoder was designed, constructed, and evaluated for failsafe and error correction capabilities under stationary gaussian noise conditions. It employs a random error-correcting (73,45) cyclic code in a binary erasure channel. The code is in the class of difference set cyclic codes. Discussed are trade-offs between failsafe communication and efficiency of transmission rate. Also discussed is a special threshold detection technique for error correction purposes. Included is a brief description of the experimental system and the procedures used for computer evaluation. (Author)
