Spectrum Management Techniques using Cognitive Radios Cognitive Radio Technology

Abstract

Spectrum has been a very valuable resource in wireless communication systems. The available electromagnetic radio spectrum is getting crowded day by day due to manipulation in wireless devices and applications. Underutilization of Spectrum has become a major source of concern for each network user. The present paper attempts to portray “Spectrum Management Techniques using Cognitive Radios”, where the strength and scope of Cognitive Radio Technology are discussed. It also highlights the efficiency and effectiveness of the system when compared to conventional mode of operations. Further, the present paper also lucidly explains the modus operandus of Cognitive Radio Technology Spectrum Management Techniques namely Spectrum Sensing, Spectrum Decision-Making, Spectrum Sharing and Spectrum Mobility. These functionalities make Cognitive Radio Technology an asset to the network domain and easily solves issues like interference, noise and underutilization. The paper also focusses on describing the Transreceiver and network architecture. On the whole, this paper is an overall description about the Spectrum Management Techniques in Cognitive Radio Technology in brief.
