ABSTRACT:
An RLL demodulator for performing RLL demodulation on primary modulation data performs hard demodulation outside an iterative decoding loop. Further, decoding in compliance with a constraint concerning a PR transfer characteristic is performed by a PR-channel APP detector which performs iterative decoding by repeatedly feeding and receiving a priori information regarding the primary modulation data to and from an APP decoder for error-correcting codes.
