  • To reduce the computational complexity of spectrum sensing and improve the spectrum sensing performance, a spectrum sensing method based on the fractal box dimension was proposed. As the box dimensions of noise and signal are different, the fractal box dimension is used as test statistics. The simulation results demonstrate the proposed method has good detection performance under Gaussian white noise, and it is not sensitive to the noise. Furthermore, this method is low computational complexity and easy to implement.
