Root-Mean-Square Error in Encoded Digital Telemetry

This paper studies the effectiveness of certain group codes in reducing the root-mean-square (rms) error in a digital telemetry link. The zero-sampling-error lower bound on the total error is derived for the case when majority-logic-decodable group codes are used in the channel. Calculated data are presented for several such codes including two new cyclic unequal-error-protection codes.
