Signal space detectors for MTR-coded magnetic recording channels

Hamid R Shafiee; Bernardo Rub; Robert E. Kost

In this paper, we present signal space detectors for use with maximum transition run (MTR) codes. A three-dimensional signal space detector Is first derived for an MTR=2 coded channel. The bit error rate performance of this detector is close to MTR-coded FDTS/DF(2) throughout the user density range of interest. The detector is then modified to be used with a time-variant MTR code. Simulation as well as experimental results are presented.
