摘要： The invention describes a code generation method, an encoding method, an encoding apparatus, and extended versions thereof. The code generation method comprises removing columns and rows from submatrices of a given matrix, and attaching a small number of additional columns thereto. The encoding method derives a codeword v in 3 parts, one of which is the given information vector u. The remaining 2 parts of the codeword are derived in a recursive, but parallelizable way. The extended versions use the generated code in a context of parallel concatenated LDPC coding.

摘要： The invention proposes an approach, where on the recording side, after conventional error correction encoding (201), parity-check bits allowing to identify dominant error events are inserted first (202), after which the resulting bitstream is modulation encoded (203). Correspondingly, at the readback side, the parity-based post processing (208) takes place after modulation decoding (207).

摘要： The error correction capability of block codes can be doubled if error locations are known. Prior art approaches for error location detection always involve adding dedicated redundant data which then are evaluated to yield error location information.

摘要： A channel encoding method is disclosed, which comprises dk-encoding and NRZI precoding, the output of which obeys a repeated minimum transition runlength constraint and is FSM decodable with a given lookahead depth. Occurrences of RMTR violating critical bit sequences are replaced by same length replacement sequences containing extended zero runs; and the FSM decodability with a given lookahead depth is achieved by using only those replacement sequences that are decodable with the given lookahead depth. A pertaining FSM channel decoding method and channel decoding apparatus, as well as using the FSM in trellis decoding, are disclosed.

摘要： The invention relates to a method and apparatus for bit recovery from a sequence of signal samples (hf in) obtained from a recording medium, for one or more partial-response cases. In the method, a Viterbi decoder (6) is re-configured to match a target polynomial to different data channel transfer functions by adapting (22) target reference levels, making the respective target polynomial follow the real data channel. The apparatus has memory means containing distinct target reference levels (TRLi) for all state transitions and partial-response cases. A state machine is employed which addresses the target reference levels by means of indexes or pointers into the memory means.

摘要： For deriving a repeated minimum transition run limited channel code and decoder from a given state transition diagram of an original code that is finite state machine decodable, run-length limited and has no repeated minimum transition run limitation, the invention proposes to identify, as RMTR violating loops, those state transitions that cause unlimited repeated minimum runs, to break the identified RMTR violating loops by inserting one additional state and by re-directing violating transitions; and to assign valid next state/output codeword pairs to the additional state for each possibility of redirecting violating transitions. The invention describes steps which guarantee that the resulting RLL code fulfills the d-constraint of the original code, is RMTR limited, and remains decodable.

摘要： The invention proposes a PR level detection method and apparatus which jointly estimate multiple PR levels (227) based on multiple channel signal samples (201, 205). Overlapping vectors of e.g. m=2 consecutive PR levels are jointly estimated based on corresponding vectors of samples. The sample vector and the associated PR level vector can directly be input to the prior art formula for estimating timing error. Alternatively, from the multiple PR values available per each time index n, a single PR level may be derived e.g. by majority vote with or without weighting. The invention also describes a compact apparatus structure for realizing the method. It employs the fact that the set of possible PR-levels is fixed, and employs a scaling factor (2) and a common term for subtraction (c1, c2).
