Summary:
It is obvious that for cognitive ratio technology the success of using it depends on how accurate of spectrum sensing is. For MIMO systems, there are multiple antennas which can be more utilized for spectrum sensing than only one antenna like conventional systems. However, in literatures, the use of multiple antennas for sensing approach is based on two-state decision; available or occupied spectrums. In this paper, multi-state decision so called soft decision has been proposed to improve the performance of spectrum sensing for MIMO systems. Also this paper proposes the integration of Equal Gain Combining and MAJORITY Rule for sensing the spectrum. The results show that the proposed technique provides the best performance in comparing with other techniques.
