  1. 21. Modeling, Control and Automatic Code Generation for a Two-Wheeled Self-Balancing Vehicle Using Modelica

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Carlos Javier Pedreira Carabel; Andrés Alejandro Zambrano García; [2011]
    Keywords : Technology and Engineering;

    Abstract : The main goal of this project was to use the Modelica features on embedded systems, real-time systems and basic mechanical modeling for the control of a two-wheeled self-balancing personal vehicle. The Elektor Wheelie, a Segway-like vehicle, was selected as the process to control. READ MORE

  3. 22. Analysis of OSTBC in Cooperative Cognitive Radio Networks using 2-hop DF Relaying Protocol

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Muhammad Mustafa Tahseen; MatiUllah Khan; Farhan Ullah; [2011]
    Keywords : Cognitive Radio; Cooperative Communication; Alamouti STBC; OSTBC; Rayleigh Fading; Energy Detector; DF Relay; Maximum Likelihood; MRC;

    Abstract : To achieve cooperative diversity in cognitive radio network, Decode and Forward (DF) protocol is implemented at Cognitive Radios (CRs) using Orthogonal Space Time Block Coding (OSTBC). The 2-hop communication between source and destination is completed with the help of Cognitive Relays (CRs) using Multiple Input Multiple Output (MIMO) technology within the network. READ MORE

  4. 23. Implementation of MIMO-OFDM System for WiMAX

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Muhammad Atif Gulzar; Rashid Nawaz; Devendra Thapa; [2011]
    Keywords : MIMO; OFDM; WiMAX;

    Abstract : Error free transmission is one of the main aims in wireless communications. With the increase in multimedia applications, large amount of data is being transmitted over wireless communications. This requires error free transmission more than ever and to achieve error free transmission multiple antennas can be implemented on both stations i.e. READ MORE

  5. 24. Distributed gateways for terabit/s satellite : Study of smart gateway diversity

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

    Author : Florian Romain Gain; [2011]
    Keywords : ;

    Abstract : Future Satcom systems will be required to provide Internet at high capacity to an increasing number of users. Because of demanding applications the throughput should approach the Tb/s. To achieve such a data rate, large bandwidths are required. So considering spectrum congestion below 15 GHz, communications should use Ka and Q/V bands. READ MORE

  6. 25. Performance Evaluation of Simple Space-Time Block Coding on MIMO Communication System

    University essay from Linnéuniversitetet/Institutionen för datavetenskap, fysik och matematik, DFM
