  1. 1. Implementation of Spectrum Analysis Functionality for IQ-Signal.

    University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Author : Gedion Biredaw Anbessa; [2020]
    Keywords : RF Measurement Techniques; Spectrum Analyzer; Synthetic Spectrum Analysis; Synthetic Instrument; Signal Processing; Vector Signal Analyzer; IQ-signal;

    Abstract : The spectrum analyzer is a standard tool used to measure signals in the frequency domain. Traditional spectrum analyzers are based on sweeping a local oscillator and using this to mix signals down to an intermediate frequency (IF) and, subsequently filter them with a filter of settable characteristics, called the Resolution Bandwidth (RBW).

  3. 2. RF BiST för att detektera IQ-imbalanser avseende överhörningseffekter för avancerade antennsystem

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Kishore Khed; [2018]
    Keywords : Technology and Engineering;

    Abstract : Internet of Things (IoT) is a network constituted by uniquely identifiable commodity objects or devices equipped with some sensing system. To achieve high data rates required for IoT devices, a modern wireless communication system, known as Advanced Antenna Systems(AAS), leads to significant improvement, by increasing not only the data rate but also spectrum efficiency and the channel capacity.

  4. 3. Towards Battery-free Radio Tomographic Imaging : Battery-free Boundary Crossing Detection

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

    Author : Abdullah Hylamia; [2018]
    Keywords : battery-free; radio-tomographic-imaging; boundary-crossing; analog-backscatter; envelope-detector; radio-frequency; batterifri; radiotomografisk avbildning; gränsöverskridande; analogbakåtskridande; kuvertdetektor; radiofrekvens;

    Abstract : Radio tomographic imaging (RTI) is a novel device-free localization technique which utilizes the changes in radio signals caused by obstruction to enable various sensing applications. However, the deployment of these applications is hindered by the energy-expensive radio sensing techniques employed in these systems. READ MORE

  5. 4. Noise measurements of a low power detector for RFID applications

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Denis Belenko; [2012]
    Keywords : ;

    Abstract : In this work we provide measurements on low power envelope detector and compare them with results predicted by theory. This envelope detector is supposed to be used as a part of low power Wake-up radio for RFID applications. In the work we were mostly interested in noise parameters and blocker effect verification.

  6. 5. Design of Ultra-Low Power Wake-Up Receiver in 130nm CMOS Technology

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Fikre Tsigabu Gebreyohannes; [2012]
    Keywords : technology; RF; architecture; sensor node; communication; Ultra-low; power; wake-up; wake up; ultra; low; receiver; wireless sensor networks; sensor; networks; wireless;

    Abstract : Wireless Sensor Networks have found diverse applications from health to agriculture and industry. They have a potential to profound social changes, however, there are also some challenges that have to be addressed. One of the problems is the limited power source available to energize a sensor node. READ MORE
