Abstract :
A coding scheme for generating dc-free sequences over the bipolar alphabet (-1,1) is proposed. The scheme is based on dc-free coding over larger alphabets. The proposed technique is used to construct several new new dc-free codes with lower encoding and decoding complexity then the existing codes with comparable rates
