  1. 6. DIFFERENTIAL CODE SHIFTED REFERENCE IMPULSE-BASED COOPERATIVE UWB COMMUNICATION SYSTEM

    University essay from Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

    Author : Shoaib Amjad; Rohail Khan Malhi; Muhammad Burhan; [2013]
    Keywords : Bit error rate; Cooperative system; Differential code shift Reference and Ultra wide band communication.;

    Abstract : Cooperative Impulse Response – Ultra Wideband (IR-UWB) communication is a radio technology very popular for short range communication systems as it enables single-antenna mobiles in a multi-user environment to share their antennas by creating virtual MIMO to achieve transmit diversity. In order to improve the cooperative IR-UWB system performance, we are going to use Differential Code Shifted Reference (DCSR). READ MORE

  2. 7. An Energy-Balancing Unequal Clustering Algorithm for Multi hop Routing in WSN

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Sheima Hassan Elamin Hamed; [2013]
    Keywords : Multi-hop routing; Energy balancing; Linear optimization; Network lifetime; Unequal clustering; Wireless Sensor Networks;

    Abstract : Energy saving is a critical issue in Wireless Sensor Networks as they have limited amount of energy and no rechargeable batteries. Clustering plays an effective role in utilization and saving of the limited energy resources of the deployed sensor nodes, where nodes are grouped into clusters and one node, called the cluster head is responsible for collecting data from other nodes, aggregates them and sends them to the BS, where data can be retrieved later.

  3. 8. Error Rate Performance of Multi-Hop Communication Systems Over Nakagami-m Fading Channel

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

    Author : Hassan Sajjad; Muhammad Jamil; [2012]
    Keywords : Signal Processing; Fading Channel; Multi-hop;

    Abstract : This work examines error rate performance of Multi-Hop communication systems, employing Single Input Single Output (SISO) transmissions over Nakagami-m fading channel. Mobile multi-hop relaying (MMR) system has been adopted in several Broadband Wireless Access Networks (BWAN) as a cost-effective means of extending the coverage and improving the capacity of these wireless networks.

  4. 9. Proof-of-Concept of Bi-directional Broadcast Communication

    University essay from KTH/Kommunikationsteori

    Author : Fatou Ndiaye; [2012]
    Keywords : ;

    Abstract : From a theoretical perspective, the bi-directional broadcast communication which follows from the network coding idea has been studied extensively in the literature. However, despite the potential gain, not much practical work has been realized. READ MORE

  5. 10. Interference Management for Stabilization of Dynamical Systems over Wireless Channels

    University essay from KTH/Kommunikationsteori

    Author : Bilal Ibrahim; [2012]
    Keywords : ;

    Abstract : In networked control systems, dynamical systems are stabilized by actions of remotely placed controllers. This involves communication between plants and controllers over wireless channel(s). READ MORE
