    摘要: Embodiments of the present invention provide optimization of read/write channels in a recording system by embedding channel optimization algorithm/procedure into the channels, or a system-on-chip (SOC) where a read/write channel is integrated with a disk drive controller, according to an Embedded Channel Optimization Solution (ECOS). In one embodiment, the ECOS comprises a setup/restore block configured to set up the read/write channel (separate or embedded in SOC) according to a pattern specified by an input received by the setup/restore block; a parameter/metric block configured to store the parameters to be optimized and a metric for each of the parameters; a metric measurement block configured to provide metric measurements based on the specified pattern; and a sweep compare select block configured to sweep each value of a plurality of values of the parameters, compare a current metric taken from the metric measurement block with a previous metric for each swept value of the parameters to identify a better metric, and select a value of each of the parameters corresponding to the better metric in order to optimize the plurality of parameters.

    摘要: Certain embodiments of the present invention are improved turbo-equalization methods for decoding encoded codewords. In one embodiment, in global decoding iteration i, the magnitude values of all decoder-input LLR values (Lch) are adjusted based on the number b of unsatisfied check nodes in the decoded codeword produced by global iteration i−1. The improved turbo-equalization methods can be used as the sole turbo-equalization method for a given global decoding session, or interleaved with other turbo-equalization methods.
