The next-generation (5G/6G) wireless communication aims to leapfrog the currently
occupied sub-6 GHz spectrum to the wideband millimeter-wave (MMW) spectrum. However …

In this paper, an experimental testbed is designed to evaluate the performance of a
bandwidth compressed multicarrier technique, termed spectrally efficient frequency division …

The ever-increasing data rate and number of connections for mobile communication offer
exciting user experiences in our everyday lives. Currently, the wireless communication …

This article presents novel solutions for suppressing passive intermodulation (PIM) distortion
in frequency-division duplexing (FDD)-based radio transceivers, stemming from nonlinear …

As new wireless communication standards seek to meet the myriad demands of today's end
users, the traditional RF transmitter chain is faced with an evolving set of challenges. To …

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 …

The goal of the work presented in this paper is to demonstrate an efficient method of
amplifying multiple concurrent signals over a large bandwidth using a supply modulation …

Carrier aggregation will be a key feature of the emerging 802.11 ax system to boost data
rate. Voltage-controlled oscillator (VCO) pulling and crosstalk between RF channels are two …

This paper proposes a compact and low-cost architecture with only a single feedback loop to
implement concurrent dual-band digital predistortion (DPD) of power amplifiers (PAs). This …

The peak-to-average power ratio (PAPR) is one of the most serious issues to be dwelled on,
carefully, in wireless communication. It is not possible to take the advantage of multicarrier …
