2. 1. Culture and Transmission : The Technological and Cultural Reach of International Syndicated Radio

   Author : Lars Lundgren; Jan Ekecrantz; Göran Bolin; Arnt Maasø; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; culture; technology; transmission; space; time; radio; Internet; music; sound; media production; Media and communication studies; Medie- och kommunikationsvetenskap; Communication Studies; medie- och kommunikationsvetenskap;

   Abstract : The aim of this dissertation is to study the technological and cultural reach of internationally syndicated radio from the vantage point of the radio programme Solid Steel between 2000 and 2006. Solid Steel is a weekly two-hour music show originally produced and aired in London but today also broadcast by a large number of stations around the world, as well as via the Internet. READ MORE

4. 2. Cognitive Radio Networks : Elements and Architectures

   Author : Alexandru Popescu; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cognitive radio network management; spectrum access; multiconstrained routing optimization; multi-dimensional adaptation; middleware;

   Abstract : As mobility and computing becomes ever more pervasive in society and business, the non-optimal use of radio resources has created many new challenges for telecommunication operators. Usage patterns of modern wireless handheld devices, such as smartphones and surfboards, have indicated that the signaling traffic generated is many times larger than at a traditional laptop.

5. 3. Uplink Load in CDMA Cellular Radio Systems

   Author : Erik Geijer Lundin; Fredrik Gunnarsson; Oriol Sallent; Linköpings universitet; []
   Keywords : CDMA; Uplink Load; Radio Resource Management; Automatic Control; Cellular Radio; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The uplink of code division multiple access (CDMA) cellular radio systems is often interference limited. The interference originates from many users whose transmission powers are not observable for the system. READ MORE

6. 4. Coordinated Transmission for Wireless Interference Networks

   Author : Hamed Farhadi; Mikael Skoglund; David Gesbert; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interference; Wireless Network; MIMO; Coordinated Transmission; Resource Allocation; Interference Alignment; Scheduling; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Wireless interference networks refer to communication systems in which multiple source–destination pairs share the same transmission medium, and each source’s transmission interferes with the reception at non-intended destinations. Optimizing the transmission of each source–destination pair is interrelated with that of the other pairs, and characterizing the performance limits of these networks is a challenging task. READ MORE

7. 5. Model-Based Cognitive Radio Strategies

   Author : Kasra Haghighi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spectrum utilization; cognitive radio; censorship; CLAPP; sequential detection;

   Abstract : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates a new class of wireless communication devices known as cognitive radios (CR), which identify vacant spectrum and transmit accordingly. READ MORE
