31. ANFIS BASED OPPURTUNISTIC POWER CONTROL FOR COGNITIVE RADIO IN SPECTRUM SHARING
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : Cognitive radio is a intelligent technology that helps in resolving the issue of spectrum scarcity. In a spectrum sharing network, where secondary user can communicate simultaneously along with the primary user in the same frequency band, one of the challenges in cognitive radio is to obtain balance between two conflicting goals that are to minimize the interference to the primary users and to improve the performance of the secondary user.

32. OPTIMIZED FUZZY BASED POWER CONTROL STRATEGY IN COGNITIVE RADIO NETWORKS IN MULTI FADING PROPAGATION ENVIRONMENTS
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : In this thesis we have considered a cognitive radio network (CRN) with a pair of primary user (PU) and secondary user (SU) in spectrum sharing networks in path-loss and without path-loss propagation environments under identically distributed m-Nakagami fading channel. The thesis consists of three parts. READ MORE

33. Effect of Primary Network on Performance of Spectrum Sharing System over Nakagami-m Fading Channel
University essay from Blekinge Tekniska Högskola/Institutionen för kommunikationssystemAbstract : During the last few years, we have witnessed that radio spectrum is becoming a valuable and scarce resource due to the increasing demand of multimedia services. However, recent research has shown that most of the available radio spectrum is not used effectively and is wasted. READ MORE

34. The Alcyone CZT SPECT camera. Evaluation of performance using phantom measurement and Monte Carlo simulations
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Background Coronary artery disease is one of the most common causes of death. A common cardiac examination is to give a visualization of the myocardial blood flow by injecting a radio pharmaceutical and detect the radiation with a camera. The camera has for decades been using thallium doped sodium iodide (NaI(Tl)) as the detector material. READ MORE
