  2. 21. The Radio Frequency Single-Electron Transistor: Noise Properties and its Potential for Detecting Electrons on Helium

    Author : Serguei Kafanov; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; single electron transistor; Coulomb blockade; SET; radio;

    Abstract : In this thesis the noise in the single electron transistor (SET) has been investigated.The charge sensitivity for the radio frequency single electron transistor(RF-SET) was measured. The demonstrated result is better than the previouslybest reported value both at 40 mK, and at 4.2 K. READ MORE

  6. 24. Millimeter-Wave Impulse Radio

    Author : Mats Ärlelid; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compound semiconductor; resonant tunneling diode; ultra wideband; 60 GHz; on-off keying; transmitter; receiver; and super-regenerative oscillator;

    Abstract : This thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. READ MORE

  7. 25. Hybrid cellular-broadcasting infrastructure systems : radio resource management issues

    Author : Aurelian Bria; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : This thesis addresses the problem of low-cost multicast delivery of multimedia content in future mobile networks. The trend towards reuse of existing infrastructure for cellular and broadcasting for building new systems is challenged, with respect to the opportunities for low cost service provision and scalable deployment of networks.
