DC-free error correcting codes based on convolutional codes

A new class of DC-error correcting codes based on convolutional codes is proposed with its performance analysis. The proposed codes can be encoded and decoded using the conventional convolutional encoders and decoders with slight modifications. And the codes have null point at DC and capable of correcting errors. The DC-free error correcting codes are especially well suited for applications in high-speed channels.
