DC-free error-correcting codes based on partition chain are presented in this paper. The partition chain can be constructed from code partition chain of Reed-Muller codes. The line coding parameters for the partition chain such as maximum runlength and running digital sum are obtained. The trellis and multilevel code structure can be used to design the DC-free error-correcting codes. Especially, by adopting DC-free trellis codes as constituent codes, DC-free turbo codes can be designed. As results, the presented DC-free error-correcting codes have good coding characteristics.
