Abstract |
|
Cognitive Radio (CR) Technology is the main area of research in wireless communication since it provides dynamic spectrum access (DSA), hence reduces spectrum scarcity problem. Spectrum sensing in CR technology is very challenging topic as it is the first step towards exploiting abilities of a cognitive radio for efficient spectrum usage. This review paper presents a survey on spectrum sensing techniques. Signal processing techniques and Cooperative sensing techniques along with their pros and cons have been reviewed. Advanced sensing techniques are also considered which are the extension of conventional sensing techniques for the mitigation of multipath fading effects and minimization of the time taken for sensing, hence achieving high throughputs. These include distributed spectrum sensing, sequential spectrum sensing and the quickest detection. |
