List Viterbi Decoding with Continuous Error Detection
The List Viterbi Algorithm (LVA) with an arithmetic coding based continuous error detection (CED) scheme is applied to high-order partial-response magnetic recording channels. Commonly used magnetic recording systems employ distance-enhancing codes along with parity-check post-processors to correct most dominant error events. The system presented here inserts a CED encoder between the outer Ree...

متن کاملEmbedding Noise Prediction into List-Viterbi Decoding using Error Detection Codes for Magnetic Tape Systems
A List–Viterbi detector produces a rank ordered list of the N globally best candidates in a trellis search. A List–Viterbi detector structure is proposed that incorporates the noise prediction with periodic state-metric updates based on outer error detection codes (EDCs). More specifically, a periodic decision making process is utilized for a non-overlapping sliding windows of P bits based on t...
متن کاملJoint turbo channel detection and RLL decoding for (1, 7) coded partial response recording channels
Runlength limited (RLL) codes are essential in recording systems for minimizing distortions and maintaining bit synchronization. In this paper, we investigate the application of turbo codes on RLL (1, 7) coded partial response equalized recording channels. We propose a ‘combined trellis’ approach for doing ‘soft-in soft-out’ (SISO) channel detection and RLL decoding jointly. This approach makes...
متن کاملBlock Error Probability using List Viterbi Decoding with Hard Decisions
We consider the List Viterbi Algorithm (LVA) for block decoding of a concatenated channel coding system. The inner code is either convolutional or rate compatible punctured convo-lutional (RCPC), and the outer code is a cyclic redundancy check (CRC). The block error probability is deened as the probability that the transmitted sequence is not in the list of L candidates considered by the LVA. W...
