  1. 11. A Study of Multiband Indoor Radio Distribution System

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Bikash Shakya; [2015]
    Nyckelord :;

    Sammanfattning : The mobile indoor traffic are increasing exponentially which is the current challenge inindoor coverage and design for most of the researchers and business companies todevelop further. There are different trade-off to provide different indoor services withthe use of different repeater system, distributed antenna network (active and passive),macro cells indoor penetrations and many more.

    Sammanfattning : In the field of signal processing adaptive filtering is a major subject which has vast applications in speech processing e.g. speech coding, speech enhancement, echo cancellation and interference. Echo is the major problem in the communication systems. LÄS MER

  4. 13. Integrated Multiband High Gain and Stable GaN Input Matching Network

    Kandidat-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Alexander Karlsson; Alexander Vestlund; [2013]
    Nyckelord :;

    Sammanfattning : This bachelor thesis covers the basics of constructing a stable transistor based amplifying circuit. The task was to design an input match in order to increase the gain of a specific transistor. This transistor model, GH60015D is developed by Cree Inc. When this transistor is stabilized much of the original gain is reduced. LÄS MER

    Sammanfattning : Remarkable equipment development in the field of communication and the growing end user requirement has lifted the need for multi-functional wireless communication devices. Since antenna is the basic part of each wireless communication scheme and multi-functional antennas are looked-for to meet up the requirements of present progress, those be able to sustain compound functions in a particular antenna constituent by sustaining other than one operational frequency .
