Enhanced adaptive threshold for cognitive radio
J. Avila, Sri Rudra, K. Manoj Reddy · 2017
Wireless communication users are increasing day by day which in turn leads to scarcity for spectrum. In order to overcome this problem, cognitive radio is the booming solution. Cognitive radio (CR) is an intelligent radio that can be programmed and configured dynamically. One of the important tasks of cognitive radio is to sense the free spectrum. The availability of the signal is decided by comparing it with a predefined threshold. The threshold value cannot be too high or low as it causes probability of missed detection and probability of false alarm problems. So care should be taken in calculating the threshold value. Hence this paper aims to calculate the proper threshold value for efficient decision making so that efficient spectrum utilization could be achieved.
