The limited available spectrum and the inefficiency in the spectrum usage necessitate a new communication paradigm to exploit the existing wireless spectrum opportunistically. This new networking paradigm is referred to as cognitive radio(CR) networks. In CR networks, one of the main challenges in open spectrum usage is the spectrum sensing before it is shared by different users. In this paper, we describe an optimization of an efficient sensing technique-Parallel Cooperative Spectrum Sensing.
