“…If the spectral properties of the signal to be detected are known, but the signal has otherwise no usable features that can be efficiently exploited, then spectrum estimation techniques like filterbankbased detectors may be preferable [3], [36]- [38]. In addition, if the cognitive radio system exploits a filter bank multicarrier technique, the same filter bank can be used for both transmission and spectrum sensing [36].…”

“…The multitaper method (cf. [37] or [38]), uses the so-called Slepian sequences also known as discrete prolate spheroidal wave functions as prototype filter coefficients. The Slepian sequences are characterized by two important properties: i) they have maximal energy in the main lobe, and ii) they are orthonormal.…”

“…Spectrum sensing is defined as the task of finding spectrum holes by sensing the radio spectrum in the local neighborhood of the CRN in an unsupervised manner [24]. Spectrum holes, i.e.…”

“…With the rapid growth of wireless systems and devices, the radio spectrum becomes scarce and recent research certifies that at any particular spatial region and time, spectrum is often heavily underutilized [1][2]. This vacant spectrum can opportunistically be utilized by the CR which permits the radio users to share their radio resources following improved spectrum efficiency.…”
