Abstract(in English) | This paper presents a weighted diversity combining technique for cyclostationarity detection based spectrum sensing of orthogonal frequency division multiplexing (OFDM) signals in cognitive radio. In general weighted combining techniques of radio communication systems, a received signal is weighted, therefore, a noise component including the received signal is also weighted in the same way as a signal component. A cyclic autocorrelation function (CAF) is used for cyclostationarity detection based spectrum sensing, and signal and noise component of the CAF can be obtained individually in sensing procedure. In this paper, we attempt to improve sensing performance to use the different weight for signal and noise components of the CAF. The presented results are compared with some conventional results, and these results show that the presented technique can improve the spectrum sensing performance. |
