In contrast with the general case, where only the signal detection aspect is considered, the problem of spectrum sensing as seen from a cognitive radio perspective has very

We define δ as the delay between the sampling instant of two consecutive BCS (so if the first BCS samples at instant nT s , the i-th BCS samples at instant nTs + i ( − 1 ).

The modal analysis based on the zeros and poles repre- sentation of the input impedance by a rational fraction is a classical technique for antennas study [19]. The eigenmodes
