A new wideband adaptive digital predistortion technique employing feedback linearization

open access: yes, 2019
We develop a new wideband digital feedback predistortion (WDFBPD) technique for modulated signals with wide bandwidths by combining digital feedback predistortion (DFBPD) linearization and memory-effect compensation techniques.

Digital predistortion of power amplifiers using structured compressed-sensing Volterra series [PDF]

open access: yes, 2017
Digital predistortion has become an attractive technique for power amplifier linearisation whose limiting factor for using Volterra series as the underlying model is its computational complexity, since the number of components rapidly grows with the non ...

Real-Time 262-Mb/s Visible Light Communication With Digital Predistortion Waveform Shaping

open access: yesIEEE Photonics Journal, 2018
A digital predistortion waveform shaping scheme combined with a blue filter is proposed to optimize both the rise and fall times of a light-emitting diode (LED) and the optical receiver current of the signal of the real-time visible light communication ...

Neuro-fuzzy Approach to Adaptive Digital Predistortion

open access: yes, 2004
A neuro-fuzzy approach to adaptive digital predistortion is presented. The hybrid approach is called adaptive neuro-fuzzy inference system and uses real-time modelling of the power amplifier responses. Measurement results show that the linearity of a two-
