Cognitive Radio is a promising way to overcome the spectrum scarcity for wireless communication and improving the spectral efficiency by using the vacant licensed spectrum band. Non-Cooperative communication is a new communication technique which utilizes the help of neighboring nodes to reduce the bit error rate (BER) in a harmful fading environment. The challenging factor is to combine the Non-cooperative communication in cognitive radio to improve the spectral efficiency and to reduce the BER factor of unlicensed user’s communication. In this paper, a comparative study of different communication techniques are done by considering Rayleigh fading channel environment and the advantages of non-cooperative communication is analyzed.
