On the information-theoretic capacity of magnetic recording systems in the presence of medium noise

  title={On the information-theoretic capacity of magnetic recording systems in the presence of medium noise},
  author={Dieter-Michael Arnold and Evangelos Eleftheriou},
The compound behavior of the magnetic recording channel is modeled by combining the Lorentzian read-back pulse, the microtrack channel model, and additive white Gaussian noise (AWGN). By noting that at the output of this model the read-back signal is cyclostationary, the average autocorrelation function and corresponding power spectral density over one period are computed. The average power spectral density is then used to characterize the capacity of the magnetic recording channel for various…

Computing information rates of magnetic recording channels in the presence of medium noise

Numerical results are provided that show that from an information theoretic viewpoint in certain cases medium noise is preferable to AWGN.

Computing information rates of finite state models with application to magnetic recording

A new and practical method is presented for computing estimates of lower and upper bounds (information rates) on the capacity of FSMs, focusing on aperiodic and irreducible FSMs whose state and observation process are stationary and ergodic.

Signal Processing for Magnetic‐Recording Channels

The state of the art in signal processing and constrained coding for hard-disk drives is reviewed, with emphasis on the techniques that have been used in commercial systems.

Multidimensional signal processing and detection for storage systems with data-dependent transition noise

It is shown that the gain in terms of BER versus signal-to-noise ratio with the detector increases with the user density, and this method improves the bit-error-rate (BER) performance with respect to previous approaches and makes the detector quite insensitive to transition noise.

Bounds on the capacity of a peak power constrained Gaussian channel

The authors present an upper bound and conjecture a lower bound on the information theoretic capacity of a digital magnetic recording channel. The channel is modeled as a linear time-invariant filter

The intersymbol interference channel: lower bounds on capacity and channel precoding loss

Several new and old lower bounds on the capacity are derived in a unified manner by assuming different front-end receiver filters, in particular the sampled whitened matched filter (SWMF) and the minimum mean-squared error-decision feedback equalizer (MMSE-DFE) filter.

Characterization of cyclostationary random signal processes

This paper examines two methods for representing nonstationary processes that reveal the special properties possessed by CS processes, and shows that the HSR is particularly appropriate for characterizing the structural properties of CS processes and that the TSR provides natural models for many types of communication signal formats.

An information theoretic approach to timing jitter

It turns out that a kind of 'distorted waterfilling' is found that, dependent on the ratio between additive and jitter noise, leads to an optimal power spectral density that peaks at the low frequencies.
