Abstract
In a method of determining an iteration value for an iterative decoding process of a hard disk drive, a bit error rate (BER) of a digital signal is measured in multiple iterations. A difference is calculated between BERs of consecutive iterations, and the calculated differences are compared with a reference value. An adjusted iteration value is then determined based on the comparison.
