| 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 is more and more important to ensure that cognitive radios would not interfere with primary users. Architecture based on filter bank allows to sense multi-channels simultaneously. Filter Bank is attracting much interests since it provides efficient implementation of bandpass filters, however the sensing performance has not been studied enough yet. In this report, we propose a multi-channel sensing architecture based on polyphase DFT filter bank followed by energy detector. The sensing performance of the architecture, including the effect of prototype filter and some design parameters are evaluated by numerical simulation as well as theoretical analysis. Also, the result is compared with the conventional FFT and sequential sensing. |
