1. 16. Comparison of Video Quality Assessment Methods

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Agata Jung; [2017]
   Keywords : Video Quality Assessment; Video Quality Prediction; Video Compression; Video Quality Metrics;

   Abstract : Context: The newest standard in video coding High Efficiency Video Coding (HEVC) should have an appropriate coder to fully use its potential. There are a lot of video quality assessment methods. These methods are necessary to establish the quality of the video. Objectives: This thesis is a comparison of video quality assessment methods.

3. 17. Parametric Coding for Spatial Audio

   University essay from KTH/MWL Marcus Wallenberg Laboratoriet

   Author : Bertrand Fatus; [2016]
   Keywords : ;

   Abstract : This thesis presents a stereo coding technique used as an extension for the Enhanced Voice Services (EVS) codec [10] [8]. EVS is an audio codec recently standardized by the 3rd Generation Partnership Project (3GPP) for compressing mono signals at chosen rates from 7.2 to 128 kbit/s (for xed bit rate) and around 5.9 kbit/s (for variable bit rate).

4. 18. 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.

5. 19. Weighted Combination of Sample Based and Block Based Intra Prediction in Video Coding

   University essay from Lunds universitet/Matematik LTH

   Author : Signe Sidwall Thygesen; [2016]
   Keywords : Video Coding; Intra Prediction; Mathematics and Statistics;

   Abstract : The latest standard within video compression, HEVC/H.265, was released during 2013 and provides a significant improvement from its predecessor AVC/H.264. However, with a constantly increasing demand for high denition video and streaming of large video files, there are still improvements that can be done. READ MORE

6. 20. Performance Analysis of a MIMO Cognitive Cooperative Radio Network with Multiple AF Relays

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Advaita Advaita; Mani Meghala Gali; [2016]
   Keywords : Cognitive radio; Cooperative communications; Space time coding; MIMO systems; Outage probability;

   Abstract : With the rapid growth of wireless communications, the demand for the various multimedia services is increasing day by day leading to a deficit in the frequency spectrum resources. To overcome this problem, the concept of cognitive radio technology has been proposed which allows the unlicensed secondary user (SU) to access the licensed spectrum of the primary user (PU), thus improving the spectrum utilization.
