DESCRIPTION:This talk focuses on an essential aspect of Green Communication
 \, i.e.\, transmitter efficiency. PA and feeder networks consume 65% of th
 e power in a base station. Reducing power consumption in PA directly impac
 ts the overall power consumption. Enhancing PA efficiency has a huge socia
 l impact by reducing the CO2 footprint in wireless network technology. It 
 is well known that 5G/6G applications have signals with high PAPR\, and ac
 hieving good efficiency in PA will be challenging in such a scenario. The 
 transmission bandwidth has increased five times in 5th-generation and beyo
 nd communication systems compared to 4G communication\, which imposes stri
 ngent conditions on power amplifier design in terms of linearity and effic
 iency. This talk presents critical challenges for implementing a lineariza
 tion solution for broadband power amplifiers. The limitations and salient 
 features of digital and analog predistortion implementation will be offere
 d. The talk will further explore implementing hybrid predistortion techniq
 ues to achieve lower implementation costs with enhanced performance. It is
  shown that for carrier aggregated broadband 5G communication signals\, th
 e proposed hybrid solution provides a lower footprint area and lowers digi
 tal signal processing cost compared to state-of-the-art digital predistort
 ion solutions\, which is a lucrative offering for mmWave and terahertz com
 munication systems. In addition\, proposed techniques are evaluated for MI
 MO and beamforming applications for 5G/6G applications while considering t
 he cost of digital implementation into consideration. An innovative applic
 ation of the PA digital linearization technique is shown for multiplier no
 nlinearity\, where the C-band signal is upconverted to the mmWave signal w
 ithout additional LO\, hence providing low-cost mmWave signal generation.\
