Abstract
We introduce an adaptive equalization technique that compensates for the channel nonlinearities causing asymmetric eye-patterns of RF signals in a digital versatile disk (DVD) system. Based on the observation that a DVD channel can be modeled as a cascade of modulation transfer function (MTF) and a zero-memory nonlinearity (ZNL), an adaptive maximum likelihhood sequence estimation (MLSE) receiver that estimates the nonlinearities and incorporates them in its metric calculation is developed. Computer simulation results demonstrate that the proposed receiver can outperform conventional MLSE when signal asymmetry is present.
