Spectrum sensing is an important step toward enabling dynamic spectrum access in cognitive radio networks. To ensure that primary users are properly protected while maximizing the performance of secondary users, most related work considers the metrics of probabilities of missed detection and false alarm for determining optimal spectrum sensing parameters.(More)

BACKGROUND & OBJECTIVE Judging tumor residue of hepatocellular carcinoma (HCC) after treatment of transcatheter arterial chemo-embolization (TACE) combined with radiofrequency ablation (RFA) by computed tomography (CT) scan is difficult; while 18-fluorodeoxyglucose-positron emission tomography/CT ((18)FDG-PET/CT) has some advantages in this aspect. This(More)
Transmission power control is one of the key enabling technologies in opportunistic spectrum sharing for secondary users to optimize their performance without incurring undesirable interference on primary users. Various optimization models and algorithms for different scenarios and design objectives have hence been proposed in related work. While ideally(More)
In this paper, we consider a university campus that has an established infrastructure for supporting SIP-based VoIP service through the campus wireless data network. The campus WIAN, however, does not have 100% full coverage, and hence users cannot make untethered VoIP calls anywhere on campus. The goal of this paper is to overcome the limitations of such(More)
