Realization Complexity of a Viterbi Decoder for a Partial Response Equalized Magnetic Channel

摘要：

To retrieve information of magnetic storage, a detector is usually designed for processing the received signal. However, the nonlinear effects arise and limit the performance of the detector at a higher recording density. Fortunately, several models have been proposed to describe the nonlinear effects; and a partial response maximum sequence likelihood (PRML) detector, often realized by the Viterbi algorithm, can be applied for data detection. The realization complexities of a Viterbi decoder for different channel models are analyzed. The realization complexity of the Viterbi detector for the new representation is comparable to those of the simple partial erasure model (SPEM) and linearized model.
