Abstract

In current day wireless communication has become the most popular communication. Because of this growing demand on wireless applications has put a lot of constraints on the available radio spectrum which is incomplete and expensive. In permanent spectrum assignments there are many frequencies that are not being accurately used. So cognitive radio helps us to use these idle frequency bands which are also called as White Spaces. This is an exceptional approach to improve exploitation of radio electromagnetic spectrum. In Establishing the cognitive radio there are four important methods. In this paper we are going to discuss about the first and most important method to implement cognitive radio i.e., spectrum sensing. The challenges, issues and techniques that are involved in spectrum sensing will discussed in detail.
