1. 16. Implementing Linear Predictive Coding based on a statistical model for LTE fronthaul

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

   Author : Ghassan Nakkoul; Mohammad Shohag Hassan Kaikobad; [2016]
   Keywords : Entropy; LTE fronthaul; RRH; BBU; C-RAN; Quantization; LTE downlink; Cyclic prefix; LPC; EVM; OFDM; Linear predicting coding; LTE; Technology and Engineering;

   Abstract : This thesis studies the application of Linear Predictive coding (LPC) in the downlink of Long Term Evolution (LTE) fronthaul, which comprises of BBU and RRH. This can act as an additional module in the existing system. Today, the transmission of a single complex sample from the BBU to the RRH consumes 30 bits. READ MORE

3. 17. Compression efficiency of different picture coding structures in High Efficiency Video Coding (HEVC)

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Johan Bartelmess; [2016]
   Keywords : GOP; Group of pictures; structure; hierarchical; HEVC;

   Abstract : Video content is expected to account for 80 percent of all Internet traffic in 2019. There is therefore an increasing need for better video compression methods, to decrease the use of internet bandwidth. One way of achieving high video compression is to predict pixel values for a video frame based on prior and succeeding pictures in the video. READ MORE

4. 18. Dynamic Predictors for Content Selection in Content Distribution Networks

   University essay from KTH/Reglerteknik

   Author : Fabrice Edgar Ndjamoy Nzoudja; [2014]
   Keywords : ;

   Abstract : Caching in Content Delivery Network is one of the leading methods for saving and providing Quality of Services to users in terms of low latency experienced when requesting multimedia resources. Caching allows a parsimonious use of bandwidth for service providers to have a scalable system and avoid network congestions. READ MORE

5. 19. Quantization Effects Analysis on Phase Noise and Implementation of ALL Digital Phase Locked-Loop

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Jue Shen; [2011]
   Keywords : All Digital Phase-Locked Loop ADPLL ; Quantization Step; Non-linear quantization effect; Non-linear PLL noise model; Phase Noise; Matlab Modeling; Verilog Behavior Modeling.;

   Abstract : With the advancement of CMOS process and fabrication, it has been a trend to maximize digital design while minimize analog correspondents in mixed-signal system designs. So is the case for PLL. PLL has always been a traditional mixed-signal system limited by analog part performance. READ MORE

6. 20. Residual Energy Monitoring in WirelessSensor Networks

   University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

   Author : Daniel Kifetew Shenkutie; Prashanth Kumar Patil Shinde; [2011]
   Keywords : Energy Monitoring; Sensor node energy model;

   Abstract : Since wireless sensor networks are energy constrained, introducing a method that facilitates the efficient use of the available energy in each node is a fundamental design issue. In this work, a mechanism to monitor the residual energy of sensor networks is proposed. READ MORE
