—Cognitive Radio (CR) challenges the traditional task of spectrum sensing with requirements of reliability, efficiency and real-time. Sub-Nyquist sampling has been considered for this task in order to cope with the sampling rate bottleneck of the wideband signals a CR usually deals with, by exploiting their multiband structure. However, communication(More)
—Distributed collaborative spectrum sensing has been considered for Cognitive Radio (CR) in order to cope with fading and shadowing effects that affect a single CR performance, without the communication overhead of centralized cooperation through a fusion center. In this paper, we consider collaborative spectrum sensing by a distributed network of CRs from(More)
