1. 6. Modeling Analog to Digital Converters at Radio Frequency

   Författare :Niclas Björsell; Peter Händel; Niclas Keskitalo; Linus Michaeli; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ADC; Analog to Digital Converters; Signal processing; Telecommunication; Telekommunikation; Electronics;

   Sammanfattning : Det här arbetet handlar om att ta fram beteendemodeller av analog till digital omvandlare avsedda för tillämpningar i radiofrekvensområdet. Det gäller tillämpningar inom telekommunikation men även in test- och mätinstrument där omvandlingen från analoga till digitala signaler ofta är en prestandamässig flaskhals. LÄS MER

3. 7. CMOS Transceiver Front-Ends in Mobile Communication Handsets : Architectures and Building Blocks

   Författare :Ellie Cijvat; Henrik Sjöland; Pietro Andreani; Pieternella Cijvat; Lund University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RF CMOS; Wireless Communication; Receiver; Transmitter; Power Amplifier; Harmonic Distortion; Electrical engineering; Elektroteknik; Telecommunication engineering; Telekommunikationsteknik; Electrotechnology; Elektroteknik alt Electrical engineering; RF CMOS; Wireless Communication; Receiver; Transmitter; Power Amplifier; Harmonic Distortion; Electrical engineering; Elektroteknik; Telecommunication engineering; Telekommunikationsteknik;

   Sammanfattning : For mobile communication systems in the low-GHz range, CMOS has increasingly become the technology of choice, and the level of integration in mobile handsets has risen. The use of off-chip components, which increases the handset assembly time and costs, is preferably avoided. LÄS MER

4. 8. NFV Service Chains at the Speed of the Underlying Commodity Hardware

   Sammanfattning : Link speeds in networks will in the near-future reach and exceed 100 Gbps. While available specialized hardware can accommodate these speeds, modern networks have adopted a new networking paradigm, also known as Network Functions Virtualization (NFV), that replaces expensive specialized hardware with open-source software running on commodity hardware.

5. 9. Overload control strategies for distributed communication networks

   Författare :Maria Kihl; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource allocation; simulation models; TINA; Intelligent Networks; distributed systems; performance analysis; overload control; Telecommunication engineering; Telekommunikationsteknik;

   Sammanfattning : In distributed communication networks several nodes interact to carry out services. New telecommunication networks support a variety of services, much different from traditional telephony. Each service has its own so called load profile, which means that the amount of capacity needed to complete a service varies. LÄS MER

7. 10. Dynamic Traffic Control in Multiservice Networks - Applications of Decision Models

   Författare :Ulf Ahlfors; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed-Memory Systems; Overload Control; Call Admission Control; Routing; Optimization; Multiservice Networks; Markov Decision Process; Telecommunication engineering; Telekommunikationsteknik;

   Sammanfattning : In this thesis, we develop and examine decision models intended for traffic engineering analysis of multiservice networks. Two important issues are addressed, namely call admission and routing control in multiservice broadband networks, and overload control in distributed-memory systems. LÄS MER
