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....
