Wideband spectrum sensing based on group testing utilizing polyphase filter banks
A wideband spectrum sensing procedure based on the idea of group testing is proposed in this paper. A new polyphase filter bank (PFB) for which the output subbands have the same bandwidth and contain continuous frequency components is proposed. This PFB is utilized to form a two-stage wideband spectrum sensing method. The simulations show that the proposed method can reduce the number of binary tests greatly when the number of occupied primary channels is low.
