| Abstract(in English) | This paper presents a cyclic autocorrelation function (CAF) diversity combining technique for spectrum sensing by test statistics sharing among mutiple receive antennas with time averaged weights. We have presented a weighted CAF diversity combining technique, however, weight factor used in this technique has noise component. Hence, noise component included weight factor has a negative influence on the performance of false alarm probability. For this reason, it is reduced that noise component included weight factor by averaging a large number of CAF, and we attempt to improve the performance of spectrum sensing. The presented results are compared with results obtained using some conventional techniques and they show that performance of detection be significantly improved. |
