Globally considered as one of the key technologies in the field of wireless communications, cognitive radio has the capability to solve the issues related to radio spectrum scarcity with the help of dynamic spectrum allocation.

It discusses topics including software defined radio architecture, linear predictive coding, variance fractal compression, optimal Codec design for mobile communication system, digital modulation techniques, spectrum sensing in cognitive radio networks and orthogonal frequency division multiplexing in depth. The text is primarily written for senior undergraduate and graduate students, in learning experimental techniques, designing and implementing models in the field wireless communication.


Rajeshree Raut is currently working as an Associate Professor in the Department of Electronics and Telecommunications Engineering at Government College of Engineering, Nagpur.

Ranjit Sawant is currently working as the Vice Principal, Government Polytechnic, Hingoli, Maharashtra, India

M. Shriraghavan is currently working towards his PhD from Vignan's Foundation for Science, Technology & Research, Vadlamudi, Guntur District, Andhra Pradesh.
