【 摘 要 】

A block code of the form (2p)B(2p+1)B cannot provide both d.c. balance and redundant codewords for control signals. We describe a new set of additional rules that may be applied to groups of consecutive codewords in order to provide both d.c. balance and a large control space, and show how 256 10-bit control symbols may be achieved with a d.c. balanced 4B5B code 4 Pages
