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

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

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

    Abstract : 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. READ MORE

  5. 5. Practical Aspects of Reduced Complexity LDPC Decoding using Forced Convergence

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

    Author : Muhammad Umar Farooq; Maria Garcia Garcia; [2016]
    Keywords : LDPC; Forced Convergence; Decoding; OFDM; IEEE802.11; Technology and Engineering;

    Abstract : This thesis is an extension to the previous work done at Department of EIT in investigating the complexity reduction of LDPC decoding using the stochastic approximation method to improve the energy efficiency of energy-limited applica- tions, such as in mobile phones. The research carried out in this thesis investigates the complexity and conver- gence results of adaptive performance control algorithm (PCAA) that changes the forced convergence threshold in OMS LDPC FC decoding algorithm.
