Abstract
A new class of DC-free codes of odd length is presented. The new codes, related to polarity-switch (PS) codes, make use of a redefinition of the running digital sum. The spectral efficiency of the new codes is determined, and it is shown that they provide better power suppression in the low-frequency region than classical PS codes
