A correct and accurate model of an optical storage system is very important in the development and performance evaluation of various data detection algorithms. In this paper, we present a nonlinear modeling of a super-resolution near-field structure (super-RENS) read-out signal using the simplicial canonical piecewise-linear (SCPWL) model. The validity of this model is tested using radio frequency...
Orthogonal frequency division multiplexing (OFDM) is an attractive technique for achieving high-bit-rate wireless data transmission. However, multicarrier systems such as OFDM show great sensitivity to nonlinear distortion. In this paper, we propose a simplicial canonical piecewise-linear (SCPWL) model based digital predistorter to compensate for nonlinear distortion introduced by a high power amplifier...
In this paper, we propose a novel peak-to-average power ratio (PAPR) reduction scheme, which requires no change of a receiver structure or no additional information transmission. The approach we employed is clipping in the time and frequency domains within error vector magnitude (EVM), which is a suboptimal method with lower computational complexity compared to the optimal method. The simulation results...
This paper proposes a suboptimal peak-to-average power ratio (PAPR) reduction scheme, which is based on the time- and frequency-domain clippings, and presents its performance evaluation results for the European standard for terrestrial digital video broadcast (DVB-T) system.
