Cognitive radio networks provide high bandwidth to mobile users via heterogeneous wireless architectures and dynamic spectrum access techniques.It basically avoids congestion in wireless communication by exploiting unused radio spectrum that is not significantly engaged through a licensed user.This is the most promising and efficient technique for the proper utilization of each and every frequency band.In this paper a brief introduction of different sensing techniques has been given and also the various aspects related to these techniques.Different issues related to spectrum sensing techniques and their comparison has been done in the paper.
