Abstract
Spectrum sensing is the key problem for cognitive radio systems. A fast blind sensing method on Multi-Stage Wiener Filter (MSWF) of the received signals is proposed to sense the available spectrum for the cognitive users with the help of the multiple antennas at the receiver of the cognitive users. The greatest advantage of the new method is that it requires no information of the noise power and without any eign-decomposition (or SVD). Both the simulation and the analytical results demonstrate that the proposed method is effective, and almost the same performance compare with the eigen-value based methods.
