Performance comparison of a class of multi-level DFE and PRML detectors in presence of channel nonlinearities

Non-linear transition shift (NLTS) and partial erasure (PE) are two non-linearities that degrade the performance of high-density magnetic recording channels. NLTS denotes the shift in the average position of a magnetization transition due to interaction with the preceding transitions during write pr...

More Information
Summary:Non-linear transition shift (NLTS) and partial erasure (PE) are two non-linearities that degrade the performance of high-density magnetic recording channels. NLTS denotes the shift in the average position of a magnetization transition due to interaction with the preceding transitions during write process.
