Abstract
In one embodiment, a storage-device-implemented method for estimating one or more channel parameters of a storage device including a read channel and a storage medium with a bit sequence stored on the storage medium. The method includes: (a) the storage device reading at least a portion of the bit sequence from the storage medium to generate a bit response; (b) the storage device convolving the bit response to compute an impulse response of the read channel; and (c) the storage device estimating one or more channel parameters based on the computed impulse response.
Claims20
A storage-device-implemented method for estimating one or more channel parameters of a storage device comprising a read channel and a storage medium having a bit sequence stored thereon, the method comprising:
- (a) the storage device reading at least a portion of the bit sequence from the storage medium to generate a bit response;
- (b) the storage device convolving the bit response to compute an impulse response of the read channel;
- and
- (c) the storage device estimating one or more channel parameters based on the computed impulse response.
A storage device comprising:
- a read channel;
- and
- a storage medium, wherein the read channel is adapted to:
- (a) read at least a portion of a bit sequence from the storage medium to generate a bit response;
- (b) convolve the bit response to compute an impulse response of the read channel;
- and
- (c) estimate one or more channel parameters based on the computed impulse response.
A non-transitory machine-readable storage medium, having encoded thereon program code, wherein, when the program code is executed by a machine, the machine implements a method for estimating one or more channel parameters of a storage device comprising a read channel and a storage medium having a bit sequence stored thereon, the method comprising:
- (a) reading at least a portion of the bit sequence from the storage medium to generate a bit response;
- (b) convolving the bit response to compute an impulse response of the read channel;
- and
- (c) estimating one or more channel parameters based on the computed impulse response.
