Abstract

Spectrum is a very precious resource and thus underutilization of a large part of allocated spectrum is not affordable. Where increasing demand for wireless applications has made it difficult to manage limited spectrum, allocated spectrum utilization is found to be very low. Cognitive radio is proposed as a promising solution for increasing spectrum utilization and thereby helping to mitigate spectrum scarcity. This paper introduces the present spectrum scenario highlighting the need for newer techniques of increasing spectrum efficiency. The paper briefs the background on Cognitive Radios and also discusses some crucial design aspects and applications for cognitive radios.
