Paper Abstract

Linear superposition techniques are often used to simulate waveforms in a variety of applications. In particular, superposition techniques have been used extensively to quickly and efficiently analyze readout waveforms from optical storage media. However, as storage densities increase the optical readout process exhibits nonlinear characteristics that are not reproduced using linear superposition techniques. Alternative approaches, based on curve fitting and optimization routines, are often used to predict more accurately the readout waveform. This paper describes a novel technique for accurately simulating readout waveforms from high-density optical storage media, based on the superposition of isolated pulse responses and nonlinear signal components that arise due to inter-symbol-interference in the readout waveform.
