Abstract
The methods to enhance the performance of communication systems is on the rise. New innovations are required to achieve improved performance. As radio frequency (RF) power amplifier (PA) is one of the important block of communication system, so any improvement in the PA performance will definitely contribute to increase the overall communication system performance. PA is a non-linear device. To increase its performance, one has to linearize its response. For this various linearized techniques are available. So this paper gives an overview of the linearized techniques, which can be used to increase the PA performance by mitigating the non-linear effects. A comparative performance analysis of the linearized techniques have been done in this paper to find out the most suitable technique for wireless communication.
