Digital communication systems such as digital radio and cellular communication systems, and high speed modems such as CyberSurferTM, generally, perform data communication over an unreliable physical medium and therefore, must perform data validation. Traditional methods use checksums which are vulnerable to swap errors to detect transmission errors. This paper describes a highly reliable, low overhead method of detecting trans- mission errors by utilizing multiple overlapping checksums.
