Low computational complexity spectrum sensing based on cyclostationarity for multiple receive antennas is proposed. The proposed technique does not calculate certain test statistics at all receive antennas, as opposed to conventional techniques that perform calculations at all receive antennas. Therefore, a low computational complexity can be achieved for sensing. Numerical examples verify that the proposed technique can obtain favorable sensing performance, even with the low computational complexity.
