This work designs sequence detectors for channels with intersymbol interference (ISI) and
correlated (and/or signal-dependent) noise. We describe three major contributions.(i) First …

Rapid advances in recording materials, read/write heads, and mechanical designs over the
last 15 years have led to the need for more complicated signal processing, coding, and …

Maximum and near-maximum likelihood sequence detectors in signal-dependent noise are
discussed. It is shown that the linear prediction viewpoint allows a very simple derivation of …

The classical Blahut-Arimoto algorithm (BAA) is a well-known algorithm that optimizes a
discrete memoryless source (DMS) at the input of a discrete memoryless channel (DMC) in …

We propose a system for magnetic recording, using a low density parity check (LDPC) code
as the error-correcting-code, in conjunction with a rate 16/17 quasi-maximum-transition-run …

This paper derives closed-form expressions for modeling a magnetic recording channel with
transition noise. The closed-form expressions assume matched filtering, a Lorentzian …

The magnetic recording industry is perennially trying to grow the areal density by optimizing
the head/media, the coding/signal processing, and the bit length (BL) and track pitch (TP) of …

In this paper, we provide a survey of the novel read channel technologies that found their
implementation in products over the past decade, and we outline possible technology …

Various embodiments of the present invention provide systems and methods for data
regeneration. For example, a system for regenerating data is disclosed. The system includes …

An iterative inter-track-interference (ITI) cancelling scheme is described for multi-track signal
detection in shingled-write-recoding systems. This multi-track iterative ITI canceller consists …
