  1. 1. Texture Analysis and Ultra high-frequency ultrasound in use for diagnosing Hirschsprung's disease

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Sophia Klarén; Jonathan Jedhammar; [2023]
    Nyckelord :Hirschsprung s disease; Aganglionosis; UHF ultrasound; Texture analysis; Nakagami; Skewness; Kurtosis; Technology and Engineering;

    Sammanfattning : An investigation into the use of statistical texture analysis in combination with ultra high-frequency ultrasound for diagnosing Hirschsprung’s disease (HD); An illness that manifests itself through the absence of ganglia cells in lower parts of the intestine. Current diagnostic techniques carry a higher risk of long-term consequences in newborns and children which enables a new avenue of research into new methods. LÄS MER

  3. 2. Adaptive Modulation Coding Scheme in Amplify and Forward Relay Networks

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Nirnay Reddy Nallavelli; Sushma Swaraj Chilupuri; [2022]
    Nyckelord :Adaptive Modulation; Modulation and Coding Schemes; Amplify and Forward; Signal to Noise Ratio; Nakagami-m Distribution.;

    Sammanfattning : Wireless communications have become an essential part of our daily life. Despite the fact that wireless networks are simple to set up and deploy, the channel conditionsin wireless networks are susceptible to fading and attenuation, thereby reducing the transmission efficiency and reliability.

  4. 3. Decode and Forward Relay Assisting Active Jamming in NOMA System

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Lakshmikanth Akurathi; Surya Teja Reddy Chilluguri; [2022]
    Nyckelord :Physical Layer Security; Power-domain NOMA; Decode and Forward Relay; Jamming in NOMA; Nakagami-m Fading; Relay Transmission; Secrecy Performance.;

    Sammanfattning : Non-orthogonal multiple access (NOMA), with its exceptional spectrum efficiency, was thought to be a promising technology for upcoming wireless communications. Physical layer security has also been investigated to improve the security performance of the system. LÄS MER

  5. 4. Performance of a Non-Orthogonal Multiple Access System with Full-duplex Relaying over Nakagami-m Fading

    Master-uppsats, Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Författare :Rahul Chowdary Erpina; Viswakanth Reddy Gopireddy; [2021]
    Nyckelord :NOMA; Full Duplex Relaying; Nakagami-m Fading; Power domain NOMA; Successive Interference Cancellation; Half Duplex Relaying; OFDMA; Code domain-NOMA; Time domain-NOMA.;

    Sammanfattning : In our thesis work, we analyze the performance analysis of a power domain NonOrthogonal Multiple Access (NOMA) system in which the closer user acts as fullduplex relaying to forward the signal to farther user. Because Nakagami-m distribution is a generalized case including the two common fading distributions as specialcases: Rayleigh distribution (m=1), Rician distribution (m>1). LÄS MER

  7. 5. The Effect of Radio Channel Modelling on the Network Performance in VANET

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Md Ashraful Islam; Nasimul Hyder Maruf Bhuyan; [2015]
    Nyckelord :VANET; Routing protocol; Unicast; Broadcast; NS-3.; Technology and Engineering;

    Sammanfattning : Research in vehicle-to-vehicle communication and the Vehicular Ad Hoc Network (VANET) are two major fields of growing interest. The advent and recent development of these concepts foster evolution of the new paradigm of the transportation system, widely known as Intelligent Transport System (ITS). LÄS MER
