Design of efficient balanced codes
Sulaiman Al-Bassam, B. Bose · IEEE Transactions on Computers · 1994
All words in a balanced code have equal number of ones and zeros. Denote by DC(n,k) a balanced (or dc-free) code of length n, and 2/sup k/ code words. We design an efficient DC(k+r, k) code with k=2/sup r+1//spl minus/0.8/spl radic/(r/spl minus/2). These codes are optimal up to the construction method, introduced by D.E. Knuth (1986).>
