  1. 1. Objective Perceptual Quality Assessment of JPEG2000 Image Coding Format Over Wireless Channel

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Bala Venkata Sai Sundeep Chintala; [2019]
    Nyckelord :Discrete Wavelet Transform DWT ; Image Coding Format; JPEG2000; Objective Perceptual Quality assessment; Quality of Experience QoE ;

    Sammanfattning : A dominant source of Internet traffic, today, is constituted of compressed images. In modern multimedia communications, image compression plays an important role. Some of the image compression standards set by the Joint Photographic Expert Group (JPEG) include JPEG and JPEG2000. LÄS MER

  2. 2. Performance of physical layer security with different service integrity parameters


    Författare :Akhila Naga Sree Ravali Padala; Kavya Kommana; [2018]
    Nyckelord :Physical layer security; outage probability; symbol error rate; secrecy capacity;

    Sammanfattning : Information security has been a very important issue in wireless networks. With the ever-increasing amount of data being exchanged over wireless networks, the confidentiality of information needs to be protected from unauthorized users called eavesdropper. LÄS MER

  3. 3. Intelligent Beam Weight Computation for Massive Beamforming

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling; Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Rohan Appilla Chakravarthula; Chaithanya Kumar Reddy Veluru; [2017]
    Nyckelord :;

    Sammanfattning : LTE (Long Term Evolution) is likely the most complex wireless system ever developed. It incorporates features that could not have been economically implemented as recently as a decade ago. Today, with large-scale ICs, LTE can be easily accommodated in base stations and battery-powered handsets alike. LÄS MER

  4. 4. A comparison of Polar Code Constructions and Punctur-ing methods for AWGN and Fading channels

    Master-uppsats, KTH/Teknisk informationsvetenskap

    Författare :Jonas Sedin; [2017]
    Nyckelord :;

    Sammanfattning : Today 5G and other wireless standards are being developed for the future of our society. The different use-cases of future wireless services are going to be ever-more demanding, whether it is vehicular communication or low-powered sensor networks. LÄS MER

  5. 5. Perceptual Image Quality Prediction Using Region of Interest Based Reduced Reference Metrics Over Wireless Channel

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Kunadha Raju R V Krishnam Raju; [2016]
    Nyckelord :Reduced Reference Metric; Visual Attention; Rayleigh Fading; Quality of Experience; Image Quality Assessment.;

    Sammanfattning : As there is a rapid growth in the field of wireless communications, the demand for various multimedia services is also increasing. The data that is being transmitted suffers from distortions through source encoding and transmission over errorprone channels. Due to these errors, the quality of the content is degraded. LÄS MER
