Abstract
In this study, we apply the canonical piecewise-linear (PWL) model to the modeling of super-resolution near-field structure (super-RENS) read-out signals because reliable and accurate channel modeling is essential for performance analysis and development of equalizers for super-RENS disc systems. To mitigate the nonlinear inter symbol interference (ISI), furthermore, we propose a canonical PWL model-based equalizer (PWLEQ) for super-RENS discs. The validity of the model and the equalizer is tested using radio frequency (RF) signal samples obtained from a super-RENS disc. The modeling experiment results verified that the canonical PWL model can be efficiently utilized for the nonlinear modeling of super-RENS systems. The raw bit error rate (BER) performance with the proposed equalizer is measured for various delays and step sizes of the canonical PWL model. We observe a marked improvement in raw BER when using the proposed equlaizer.
