  1. 1. Performance Analysis of a MIMO Cognitive Cooperative Radio Network with Multiple AF Relays

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Advaita Advaita; Mani Meghala Gali; [2016]
    Keywords : Cognitive radio; Cooperative communications; Space time coding; MIMO systems; Outage probability;

    Abstract : With the rapid growth of wireless communications, the demand for the various multimedia services is increasing day by day leading to a deficit in the frequency spectrum resources. To overcome this problem, the concept of cognitive radio technology has been proposed which allows the unlicensed secondary user (SU) to access the licensed spectrum of the primary user (PU), thus improving the spectrum utilization.

  3. 2. Shaft Current Protection

    University essay from KTH/Industriella informations- och styrsystem

    Author : Tin Rabuzin; [2015]
    Keywords : shaft current; Rogowski coil; generator protection; Merging Unit; process bus; axelströom; lagerströom; Rogowskispole; generatorskydd; Merging Unit; process bus;

    Abstract : Shaft current protection in hydro and turbo generators is an important generatorprotection issue. Currents owing in the generator shaft might damagegenerator bearings which, in turn, could reduce operating time and cause largenancial losses. Therefore, it is important to prevent operation of the generatorunder conditions of high shaft currents. READ MORE

  4. 3. Exploiting the Direct Communication Link for Enhancing Effective Capacity Performance of Cognitive Radio Relay Networks

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Md Abdul Matin Biswas; [2014]
    Keywords : Cognitive Radio; Quality of Service QoS ; Effective Capacity; Cooperative Relaying; Cognitive Relay Networks; Peak Interference Power Constraint; Delay QoS Constraint;

    Abstract : Nowadays, cognitive radio (CR) is a promising concept to improve the radio spectrum exploitation. CR has tremendous ability to enhance spectrum efficiency by allowing secondary users (SUs) to access licensed radio spectrum resource which is currently not being used by primary users (PUs).

  5. 4. Översyn av skyddsanordning samt nollpunkt för fördelningsstationen Fs Myrängen

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : AMR Elawa; [2014]
    Keywords : ;

    Abstract : This is a report of a Master’s thesis done in behalf of the local network in Stockholm, under Fortum Distribution AB. The thesis was to conduct a review of a distribution station named Fs Myrängen located in Täby. A model was created for the 11 kV network linked to the secondary side of Fs Myrängen. READ MORE

  6. 5. Performance Analysis of OSTBC with Hybrid Decode-Amplify and Forward relay network

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Kanoksak Wannatrong; Mohammed Abul Hayat; [2013]
    Keywords : Cooperative communication; symbol error rate; moment generating function; orthogonal space-time block code. ;

    Abstract : In the last few decades, the innovation of Wireless communication has been developed very fast in order to improve the performance of communication systems. Especially,a concept of Multiple Input and Multiple Output (MIMO) is purposed to fulfill a high data rate service such as high quality video conference. READ MORE
