摘要
Under the circumstances that signal and the noise have different Katz fractal dimension in frequency domain, single Secondary User can make a quick decision about the existence of the Primary User. By using the cooperation sensing method based on Katz fractal dimension in frequency domain, it can fuse the decision of multiple users and give a more reliable judgment. It is possible to enhance the detection performance, while contrast detect method of box dimension, it can get a higher probability of detection under the lower SNR situation.
