1. 21. Spatial wireless connectivity prediction for mobile robots

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : Mengchan Li; [2016]
   Keywords : RSS prediction; mobile robots; RSS gradient; wireless prediction;

   Abstract : Mobile robots, either autonomous or tele-operated have the potential of assisting humans in various situations such as during natural disasters, Urban Search and Rescue (USAR) efforts, and in Explosive Ordinance Disposal (EOD). These robots need steady wireless connectivity with their base station for control and communication. READ MORE

3. 22. 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.

4. 23. 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

5. 24. Performance Analysis of Piecewise-and-Forward Relay Network on Rayleigh Fading Channel

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Farnaz Gharari; [2015]
   Keywords : Cooperative communications; Relay Networks; Rayleigh channels; Radio communication Protocols; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

   Abstract : The rapid changes and developments in cellular and wireless networks aim to provide more reliable communications with high data rate transmission. So far, one solution which is being considered for improving the reliability and eciency of mobile communications is cooperative communications. READ MORE

6. 25. Pattern Reconfigurable MIMO Antennas for Multiband LTE Operation

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

   Author : Rui Ma; Ioannis Chountalas; [2015]
   Keywords : Technology and Engineering;

   Abstract : Nowadays, multiple antennas are becoming widely used in small mobile terminals as they can significantly improve wireless communication performance in terms of link reliability and spectral efficiency. Also, pattern reconfiguration is another new trend for antenna design as it enables the antennas to adapt to different propagation and user scenarios. READ MORE
