  1. 16. Inter-Operator Spectrum sharing in Cellular Network using Repeated Game Theory

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Omer Khogali; [2013]
    Keywords : Game theory; Repeated game; Spectrum sharing; and Cognitive radio;

    Abstract : Due to the limitation of spectrum in the network and the increasing of the demand of the spectrum in the network, spectrum-sharing techniques are used to increase the efficiency of the network. Dynamic Spectrum Sharing Network is one of the techniques that describe the intelligent networks such as Cognitive Radio networks, Cognitive Radio, and Software Defined Radios. READ MORE

  3. 17. Implementation and Analysis of Spectrum Sensing Algorithms for SIMO Links

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Techin Eamrurksiri; [2013]
    Keywords : cognitive radio; USRP; OFDM; Spectrum sensing; GLRT; SDR;

    Abstract : Cognitive radio is an autonomous transceiver that is continuously sensing theongoing communication in its environment, it then starts the communication whenever it is appropriate. Therefore, cognitive radio helps improving the spectrum utilization of the overall communication system. READ MORE

  4. 18. An Effecient Scheme in IEEE 802.22 WRAN for Real Time and Non Real Time Traffic Delay

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Nawfal Al-Zubaidi R-Smith; Khaled Humood; [2013]
    Keywords : Channel sensing; Cognitive radio; energy and feature detection; IEEE 802.22; quiet period;

    Abstract : Cognitive radio network has emerged as a prevailing technique and an exciting and promising technology which has the potential of dealing with the inflexible prerequisites and the inadequacy of the radio spectrum usage. In cognitive radios, in-band sensing is fundamental for the protection of the licensed spectrum users, enabling secondary users to vacate channels immediately upon detection of primary users.

  5. 19. ANFIS BASED OPPURTUNISTIC POWER CONTROL FOR COGNITIVE RADIO IN SPECTRUM SHARING

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Joyraj Chakraborty; Venkata Krishna chaithanya varma. Jampana; [2013]
    Keywords : ANFIS; Fuzzy inference system; spectrum sharing;

    Abstract : Cognitive radio is a intelligent technology that helps in resolving the issue of spectrum scarcity. In a spectrum sharing network, where secondary user can communicate simultaneously along with the primary user in the same frequency band, one of the challenges in cognitive radio is to obtain balance between two conflicting goals that are to minimize the interference to the primary users and to improve the performance of the secondary user.

  6. 20. OPTIMIZED FUZZY BASED POWER CONTROL STRATEGY IN COGNITIVE RADIO NETWORKS IN MULTI FADING PROPAGATION ENVIRONMENTS

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Praneeth Kumar Bejjenki; Muneeb Ahmed Goraya; Syed Fovad Moid; [2013]
    Keywords : Cognitive Radio Networks; Spectrum Sharing Networks; Power Control; Takagi-Sugeno Fuzzy Inference System; m-Nakagami fading channel; OFDM.;

    Abstract : In this thesis we have considered a cognitive radio network (CRN) with a pair of primary user (PU) and secondary user (SU) in spectrum sharing networks in path-loss and without path-loss propagation environments under identically distributed m-Nakagami fading channel. The thesis consists of three parts. READ MORE
