Abstract

This letter presents a multiple antenna based spectrum sensing via a sequential detection technique. A log-likelihood ratio test of a low computational complexity statistic is defined and we develop the sequential detection based spectrum sensing using the test. The presented technique can reduce the computational complexity by overlapping samples for the calculation of each statistic while almost maintaining the accuracy of signal detection. Numerical examples are shown to validate the effectiveness of the presented technique.
