Energy Efficient Cognitive Radio System In Cooperative Communication
Cooperative spectrum sensing has recently become an important topic for cognitive radio systems. In cognitive
users, the idle user consumes massive energy for the spectrum sensing rather than busy user. Because of this, the attraction
of cooperative spectral sensing technique in practical cognitive radio system is reduced. Hence, this paper is to develop a
partial spectrum sensing algorithm for energy efficient cognitive radio system and thereby to improve the detection
performance by using Z-Transform spectrum sensing.
Keywords- Cognitive Radio, Cooperative Spectrum Sensing, Partial Z-Transform.
