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

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

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

    Abstract : 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. READ MORE

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

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

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

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

    University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

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

    Abstract : 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). READ MORE
