Performance Analysis of Sensing Time Parameter in Cooperative Sensing Cognitive Radio
نویسنده
چکیده
Spectrum scarcity problem is well addressed by cognitive radio. The main role of spectrum sensing is to discover the empty band correctly .This is done with the help of energy detector. The sensing time is a very crucial parameter which regulates the detection probability. In this paper the impact of sensing time has been investigated. The rigorous simulations are done on sensing time parameter with varying snr and keeping probability of false alarm constant and vice versa. The simulations are done for cooperative sensing with AND and OR rule and it shows that AND rule outperforms in terms of detecting the band. Results also show that Sensing efficiency is declined with increasing sensing time.
