Hello Anish, Non-linear power amplifier modeling and pre-distortion is a vast subject.
If you want to go deep in this matter I would suggest you to take a look at Baseband polinomial models. Here a reference I have used some time ago: https://repositum.tuwien.at/handle/20.500.12708/13980 If you just need something quick, you may want to lookout for AM/PM models, such as the Saleh model. Good luck!
