Abstract

For any given alphabet of size qq, a Homopolymer Free code (HF code) refers to an (n,M,d)q(n, M, d)_q code of length nn, size MM and minimum Hamming distance dd, where all the codewords are homopolymer free sequences. For any given alphabet, this work provides upper and lower bounds on the maximum size of any HF code using Sphere Packing bound and Gilbert-Varshamov bound. Further, upper and lower bounds on the maximum size of HF codes for various HF code families are calculated. Also, as a specific case, upper and lower bounds are obtained on the maximum size of homopolymer free DNA codes.
