Abstract :
A class of DC-free codes with minimum distance 4 which offer very simple encoding and decoding procedures is presented. Spectral analysis shows that in addition to being DC-free they offer strong spectral suppression at low frequencies. A comparison with similar codes in the literature shows that they provide a good compromise solution to the design of practically realizable, high-rate, DC-free error-correcting codes with strong low frequency suppression
