A General Approach to Fully Linearize the Power Amplifiers in mMIMO With Low Complexity

A radio frequency (RF) power amplifier (PA) plays an important role to amplify the message signal at higher power to transmit it to a distant receiver. Due to a typical nonlinear behavior of the PA at high power transmission, digital predistortion (DPD), exploiting the preinversion of the nonlineari...
