Abstract :

One strong weakness of the energy detector is that it requires accurate estimation of the noise power. If the noise estimation is imperfect then the false alarm rate goes high and the detection performance worsens [9, 10]. This apparent problem with the noise can be avoided by taking advantage of its statistical property. The noise in radio receivers is known to be temporally white because the main source of it being the temperature variation in the low noise amplifier (LNA).
