Abstract
Disclosed is an apparatus for detecting a signal received from a channel signal and for transforming this signal into a binary code sequence via a signal processing apparatus, which can perform a maximum likelihood detection of the reproduced data from an optical disk with reduced complexity. Accordingly, a method to detect a signal (EBS) received from a channel signal (HF), comprises the steps of digitizing the signal received from the channel, equalizing the digitized signal (A ), generating branch metrics (b_mp, b_pm) from the equalized signal (B ), determining the minimum (b_ml) of the generated branch metrics (b_mp, b_pm), determining a merge (m−, m+, m ) from the minimum (b_ml), and generating a bitstream signal from the succession of merges (m−, m+, m
