Abstract
A maximum likelihood detection method detects a maximum likelihood path using trellis transitions when decoding a code string which is obtained by encoded data by a sliding block coding employing trellis-coded partial response (TCPR) technique. The maximum likelihood detection method includes the steps of (a) inputting the code string, and (b) detecting a maximum likelihood path with respect to the code string from state transition paths using a number of trellis transition states greater than a number of states of a state transition pattern of the sliding block code.
