Abstract :
A family of compatible high-density bipolar codes (CHDB), which allow unrestricted binary signaling on pulse-code modulation (PCM) systems, while limiting the number of consecutive 0´s in the coded sequence, are presented. CHDB compares favorably to other transmission plans with the same purpose. Examples of coding, decoding, and error monitoring hardware are given.
