Due to their numerous advantages, communications over multicarrier schemes constitute an
appealing approach for broadband wireless systems. Especially, the strong penetration of …

The unique material properties of GaN, wide bandgap, high thermal conductivity, high
breakdown voltage, high electron mobility and the device properties of GaN HEMT (High …

Characterization and linearization of RF power amplifiers (PAs) are key issues of fifth-
generation wireless communication systems, especially when high peak-to-average ratio …

Conventional radio-frequency (RF) power amplifiers operating with wideband signals, such
as wideband code-division multiple access (WCDMA) in the Universal Mobile …

This paper addresses the modeling and cancellation of self-interference in full-duplex direct-
conversion radio transceivers, operating under practical imperfect radio frequency (RF) …

In this article, a thorough overview of behavioral modeling and predistortion of dynamic
nonlinearities in RF PAs and transmitters was presented. The sensitivity of the DUT behavior …

In this paper, we propose a beam-oriented digital predistortion (BO-DPD) technique for
power amplifiers (PAs) in hybrid beamforming massive multiple-input multiple-output (MIMO) …

The RF PA, as one of the most essential components in any wireless system, suffers from
inherent nonlinearities. The output of a PA must comply with the linearity requirement …

The continuously increasing demand for wide bandwidth creates great difficulties in
employing digital predistortion (DPD) for radio frequency (RF) power amplifiers (PAs) in …

Though a large variety of efficiency structures for ray tracing exist, kd-trees today seem to
slowly become the method of choice. In particular, kd-trees built with cost estimation …
