1. 21. Full Duplex Multiuser MIMO with Massive Arrays

   University essay from Institutionen för systemteknik; Tekniska högskolan

   Author : Hussain Wannas; [2014]
   Keywords : Full-Duplex; Massive MIMO; MIMO; MU-MIMO;

   Abstract : Half-Duplex Multiuser Multiple-Input Multiple-Output (HD MU-MIMO) systemscurrently employed in communication systems are not experiencing the selfinterference(SI) problem but they are not optimal in terms of efficiency and interms of resources used (time and frequency resources). Ignoring the effect of largescalefading, we start by explaining the uplink (UL) and downlink (DL) parts ofthe MU-MIMO system and how the sum-rate is calculated. READ MORE

3. 22. Real-Time Full Duplex Communication Over the Web : A performance comparison between different web technologies

   University essay from Högskolan i Skövde/Institutionen för informationsteknologi

   Author : Elof Bigestans; [2014]
   Keywords : real-time communication; websocket; server-sent events; short polling; ajax; performance; web development; realtidskommunikation; websocket; server-sent events; upprepade hämtningar; ajax; prestanda; webbutveckling;

   Abstract : As the web browser becomes an increasingly powerful tool for the average web user, with more features and capabilities being developed constantly, the necessity to determine which features perform better than others in the same area becomes more important. This thesis investigates the performance of three separate technologies used to achieve full-duplex real time communication over the web: short polling using Ajax, server-sent events and the WebSocket protocol.

4. 23. Modeling of Avionics Systems using JGrafchart and TrueTime

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Anna Benktson; Sofia Dahlberg; [2012]
   Keywords : Technology and Engineering;

   Abstract : The first part of the thesis aims to investigate the applicability of JGrafchart and its associated Model of Computation(MoC) for describing sequential control in aircraft primary power distribution systems. The motivation behind this is the need for better modeling tools and in particular support for separation between nominal control and fault handling. READ MORE

5. 24. Flexible Audio Coder

   University essay from KTH/Ljud- och bildbehandling

   Author : Marcus Asteborg; [2011]
   Keywords : ;

   Abstract : As modern communications networks are heterogeneous and, therefore, highly variable, the design of source coders should reflect this network variability. It is desired that source coders are able to adapt instantly to any bit-rate constraint. READ MORE

6. 25. Pushing real time data usingHTML5 Web Sockets

   University essay from Institutionen för datavetenskap

   Author : Nikolai Qveflander; [2010]
   Keywords : ;

   Abstract : The current browser landscape has no real support for server initiated push. Existing technologies such as Comet and AJAX emulate server push using "long-polling" and rely on maintaining two connections between client and browser for streaming. READ MORE
