Abstract

In this paper, a new energy detection-based scheme is introduced for spectrum sensing in cognitive radio systems. This employs multiple receive antennas to mitigate the channel fading. Partial decisions are first made by employing the conventional energy detector at each antenna, based on which a final decision on the presence of the signal is reached. Performance of the proposed and conventional energy detection schemes is presented in terms of the complementary receiver operating characteristic (ROC), when considering a Suzuki channel. The effect of the sensing duration and mobile speed on the sensing performance is also investigated.
