Comparative Performance Analysis of Non-Cooperative Spectrum
Author Name : Ankita Arora, Lokesh Kumar
ABSTRACT Cognitive Radio (CR) is a wireless system that communicates in an efficient and reliable manner by sensing the environment. The main challenge in any cognitive radio system is to maximize secondary user’s throughput while limiting interference imposed on licensed users.CR has to automatically analyses its radio spectrum environment to identify temporarily vacant spectrum and use it by adapting to the environment by changing its transmission parameters. This paper presents a comparative performance analysis of three broad non cooperative SS techniques i.e. energy detection, cyclostationary detection and matched filter detection.
