| Abstract(in English) | As a growing interest in the cognitive radio technology has been taken based on the idea of opportunistic spectrum use, the spectrum sensing technique for dynamic channel environment is more and more important to ensure that cognitive radios would not interfere with primary systems while it achieves reasonable throughput opportunistically. Architecture based on filter bank allows to sense multi-channels simultaneously with low spectrum leakage from adjacent channels thanks to efficient implementation of bandpass filters. Therefore it is now attracting much interest. In this paper, we propose a framework of multi-channel sensing architecture based on polyphase DFT filter bank followed by energy detector with minimum complexity. The sensing performance is evaluated by numerical simulation as well as theoretical analysis comparing with the conventional periodogram spectral estimator and time domain sequential sensing. |
