Symbol timing recovery scheme for parallel recording channel systems |
摘要 |
A computer program product is provided for performing symbol timing recovery in a parallel recording channel system. The computer program product comprises a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a processor to cause the processor to receive a plurality of timing-error estimates for a plurality of read channels. Each of the timing-error estimates corresponds to one of the read channels. Also, the program instructions are executable by the processor to cause the processor to calculate a common phase based on the plurality of timing-error estimates. Moreover, the program instructions are executable by the processor to cause the processor to calculate a skew of a transducer array based on the plurality of timing-error estimates, and to calculate a different total phase estimate for each read channel based on the calculated common phase and the calculated skew of the transducer array. |

1. A computer program product for performing symbol timing recovery in a parallel recording channel system, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
receive, by the processor, a plurality of timing-error estimates for a plurality of read channels, each of the timing-error estimates corresponding to one of the read channels; calculate, by the processor, a common phase based on the plurality of timing-error estimates; calculate, by the processor, a skew of a transducer array based on the plurality of timing-error estimates; and calculate, by the processor, a different total phase estimate for each read channel based on the calculated common phase and the calculated skew of the transducer array. |
