Error Control for Digital Data Transmission over Telephone Networks

摘要

The results are presented of a study of error control techniques applicable to binary digital data transmission over commercial telephone networks. The investigation consisted of a study of error control algorithms, a compilation of the error statistics for digital data on telephone lines, an evaluation of the performance of the error control techniques when applied to these error statistics, and a survey of the state-of-the-art in the hardware development of error control devices. The performance to be expected from these error control algorithms was determined when applied to the actual error statistics of common carrier voice bandwidth communication channels and the feasibility of implementing these techniques. An introduction to the important considerations for selection and evaluation of error control techniques is provided. (Author)
