Abstract

In the modern era, where colossal demand for high data rate fidelity and accessibility is crucial to be provisioned by service providers, many spectrum allocation and densification schemes proposed by Cognitive Radio (CR) have been adopted. In the endeavor to nullify the impact of noise and interference so that system capacity can be increased, multiple strategies have been proposed. To enable efficient communication, optimized usage of available radio resources is essential to meet the stringent requirements of 5G as envisaged by International Telecommunication Union (ITU) in the IMT-2020 standards. Therefore, there is a constant effort among researchers to disentangle the limitation of limited resources. The various groups involved in fostering and promoting the 5G wireless standard attempt to invent new innovative technologies so that utilization of the limited available spectrum resources can be donein a rational and proficient way. By employing features of cognitive radio wireless users are empowered to reconfigure optimally their operating parameters in consonance with the nearby radio environment. This paper critically examinesthe contemporary advancement in the field of cognitive radios and tries to address the pertinent issues while managing spectrum efficacy.
