A modified Otsu’s algorithm for improving the performance of the energy detector in cognitive radio
In this paper, we present a modified Otsu’s algorithm for solving the automatic threshold estimation problem in energy detection based Cognitive Radio (CR) application. The modified algorithm was tested extensively and compared with other known algorithms using both simulated and real datasets. In...

| description | In this paper, we present a modified Otsu’s algorithm for solving the automatic threshold estimation
problem in energy detection based Cognitive Radio (CR) application. The modified algorithm was tested
extensively and compared with other known algorithms using both simulated and real datasets. In particular, our findings reveal that the modified algorithm provides an averagely lower false alarm rate than
the other techniques compared with in this paper. Furthermore, the results obtained show that the algorithm is independent of the bandwidth’s size, while having a total complexity of OðVÞ, where V is the total
sample size. Thus, from the results of this paper, full and effective automatic blind spectrum sensing
using an Energy Detector is possible in CR. This can be achieved at a Signal-to-Noise Ratio of 5 dB to meet
the IEEE 802.22 draft standard of PD > 90% and PFA < 10% |
