An Adaptive Baseband Digital Predistortion System for an RF Power Amplifier

In this article, a baseband digital predistortion (DPD) radio frequency (RF) power amplifier (PA), based on the complex gain compensation and adaptive algorithm, is investigated. First, the nonlinear characters of the power amplifier are described. Nex...
With the rapid growth of modern wireless communication technologies and markets, higher spectrum efficiency is required for higher data rates and larger capacity. As a result, high order digital modulations with high peak-to-average ratio are usually adopted to meet these requirements. Therefore, the dynamic range and linearity of the...
