Channel circuit with trained neural network noise mixture estimator

A method comprising:

• determining at least one sample from a digital read signal;
• processing the at least one sample through an instance of a neural network comprised of trained coefficients;
• outputting, from the instance of the neural network, a set of estimate values corresponding to a noise mixture in the digital read signal;
• and
• adjusting at least one parameter of a read channel based on the set of estimate values.

A data storage device comprising:

• a non-volatile storage medium;
• a channel circuit including a read channel;
• means for determining at least one sample from a digital read signal;
• means for processing the at least one sample through an instance of a neural network comprised of trained coefficients;
• means for outputting, from the instance of the neural network, a set of estimate values corresponding to a noise mixture in the digital read signal;
• and
• means for adjusting at least one parameter of the read channel based on the set of estimate values.
