  1. 1. Theory and Design of Efficient Active Load Modulation Power Amplifiers

    Författare :Han Zhou; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GaN; circulator; non-reciprocity; Doherty power amplifier; Combiner synthesis; CLMA; deep power back-off; energy efficiency;

    Sammanfattning : The increasing demand for mobile data traffic has put new challenges and requirements for the development of the wireless communication infrastructure. The performance of the RF power amplifier (PA) is, in particular, of great importance, since it is the key building block for microwave transmitters in base stations and radio link equipment.

  3. 2. Towards energy efficient protocols for active RFID

    Författare :Björn Nilsson; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RFID; active RFID; protocol; back-off; carrier sense; energy efficient; wireless networks; active tag; energy consumption; Computer engineering; Datorteknik;

    Sammanfattning : The absence of a global standard is a bottleneck when using Radio Frequency Identification (RFID) technology. This thesis explores data communication protocols for Active-RFID regarding their energy efficiency and how they can be suited to fit a large variety of applications. LÄS MER

  4. 3. Energy Efficient Protocols for Active RFID
