  1. 1. Analog Front End Development for the Large Hadron Collider Interlock Beam Position Monitor Upgrade

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Oskar Björkqvist; [2019]
    Keywords : ;

    Abstract : The interlock Beam Position Monitor (BPM) system in the Large Hadron Collider(LHC) is responsible for monitoring the particle beam position at the point of thebeam dump kicker magnets and is part of the machine protection system. Thecurrent interlock BPM system has some limitations and because of this, an upgradeproject has been initiated. READ MORE

  2. 2. Design of a Gysel Combiner at 100 MHz

    University essay from Linköpings universitet/Fysik och elektroteknikLinköpings universitet/Tekniska fakulteten

    Author : Mohamed Abdul Nazar; [2019]
    Keywords : Gysel; Power Combiner; Toroidal; Inductor; PCB; 100 MHz; Wilkinson;

    Abstract : This thesis relates to the design and implementation of a Gysel power combiner consisting of two input ports. The design is implemented using discrete (lumped) components over the conventional transmission line architecture and operates at 100 MHz. READ MORE

  4. 4. Antenna diversity with opportunistic combining

    University essay from Linköpings universitet/Linköpings universitet/Fysik och elektroteknikTekniska högskolan; Linköpings universitet/Linköpings universitet/Fysik och elektroteknikTekniska högskolan

    Author : Md. Khalilur Rahman; Chuanhui Xia; [2012]
    Keywords : ;

    Abstract : In modern telecommunication technologies, the requirement for signal reliability is higher and higher but fading is the main challenge for signal reliability. Different types of techniques have been studied to mitigate this fading but MIMO (Multiple Input Multiple Output) has been studied extensively in wireless communication systems to overcome small-scale fading, which is an efficient way to improve signal-to-noise and bit error rates.

  5. 5. Performance Analysis of Selected Cooperative Relaying Techniques

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap; Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Muhammad Afaq; Sahibzada Muhammad Faheem; [2010]
    Keywords : Cooperative communication; Relaying techniques; Amplify-and-forward; Decode-and-forward; DtF; S-DtF; MRC;

    Abstract : Recently, cooperative communication has gained significant interest due to the fact that it exploits spatial diversity and provides capacity/performance gain over conventional single- input single-output (SISO) systems. A mobile node with single antenna can cooperate with a nearby mobile node having single antenna in multi-user environment to create the effect of virtual multiple antenna system. READ MORE
