Abstract :
A methodology for comparing different detection schemes for digital magnetic recording channels is presented. This methodology builds on previous work to improve the estimates of the bit error rates and to expand the scope of the results presented. The authors compare PRML/VA, DFE, and FDTS/DF detectors under different circumstances.<>
