  1. 1. Direct Signal Interference Suppression and Target Detection for Low-Cost SDR-Based Passive Bistatic Radar

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Oskar Jonsson; [2022]
    Nyckelord :passive radar; ECA; LMS; software-defined radio;

    Sammanfattning : Passive radar is a technology for detection of targets using echoes of existing radio transmitter, such as FM-radio. Since only receivers are needed for operation, a passive radar system has the possibility of being implemented using low-cost hardware. LÄS MER

  3. 2. A Survey of the Effectiveness of a Signal In a Wireless Analog and Digital System

    Kandidat-uppsats,

    Författare :Rickard Lundholm; Zaid Bashir; Sven Kurowski; [2015]
    Nyckelord :Antenna; Analog; Digital; Wireless; Arduino Uno; FM Transmitter; nRF24; nRF24L01;

    Sammanfattning : The aim of this paper is to study the different parts of a wireless system in order to better understand the signal properties and what key factors changes the signal during its transmission. Two transmitters were created, an FM transmitter that transmits analog data and an Arudino board programed to convert data to bits before its transmission. LÄS MER

  4. 3. Channel Estimation in GPRS based Communication System using Bayesian Demodulation.

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Författare :Dileep Kumar Appana; Chinni Anil Kumar; Nagappan Palaniappan Nagappan; [2009]
    Nyckelord :Bayesian; techniques; demodulation; demodulator; GPRS; rayleigh; fading; channel; dileep; appana; chinni; anil; nagappan; palaniappan; blekinge; tekniska; högskolan; institue; technology; master; thesis;

    Sammanfattning : With the increase use of portable devices such as Personal Digital Assistants (PDA), laptops, voice and data integrated cell phones and many more, there is a need of wireless communication method using air as the medium to transmit and receive information between terminals. Radio waves propagate from transmitting antenna and travel through free space undergoing reflections, diffractions and scattering. LÄS MER

  5. 4. Near-Field Characterization of FM Transmitter Devices in Mobile Phone Applications

    Master-uppsats, Institutionen för teknik och byggd miljö

    Författare :MST Afroza Khatun; [2008]
    Nyckelord :Near field measurement; far field; FM antenna in mobile phone;

    Sammanfattning : Mobile Phone, without this we can’t think to pass a day in presence. We have found a rapid increase of mobile phone users from a few years ago till now. Day by day the modern technologies allow the mobile phone to become smaller, cheaper, and more reliable. LÄS MER
