In this paper, a novel decorrelation-based concurrent digital predistortion (DPD) solution is
proposed for dual-band transmitters (TXs) employing a single wideband power amplifier …

Hybrid beamforming multiple-input multiple-output (MIMO) system has attracted a lot of
attention in recent years since it significantly reduces the hardware cost compared to the …

This letter presents analog and digital pre-distortion hybrid linearization of a broadband
radio-over-fiber transmission system. Analog pre-distortion (APD) is used to mainly …

This paper presents the design of a power-scalable digital predistorter (DPD) for transmitter
architectures. The target is to accomplish the joint compensation of impairments due to the …

Electrical anomalies due to trapping effects in gallium nitride (GaN) power amplifiers (PAs)
give rise to long-term or strong memory effects. We propose novel models based on infinite …

Massive multiple-input multiple-output (MIMO) technology is a key enabler for future wireless
