  2. 1. On the Performance of Underlay Cognitive Radio Networks with Interference Constraints and Relaying

    Author : Charles Kabiri; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio Networks; Cognitive Cooperative Relay Networks; Underlay Spectrum Access; Interference Constraint; Outage Constraint;

    Abstract : Efficiently allocating the scarce and expensive radio resources is a key challenge for advanced radio communication systems. To this end, cognitive radio (CR) has emerged as a promising solution which can offer considerable improvements in spectrum utilization. READ MORE

  5. 3. GPS/IMU Integrated System for Land Vehicle Navigation based on MEMS

    Author : Yueming Zhao; Lars Sjöberg; Milan Horemuž; Krzysztof Gajdamowicz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS; IMU; MEMS; integration; Kalman filter; physical constraint; outlier;

    Abstract : The Global Positioning System (GPS) and an Inertial Navigation System (INS)are two basic navigation systems. Due to their complementary characters in manyaspects, a GPS/INS integrated navigation system has been a hot research topic inthe recent decade. Both advantages and disadvantages of each individual systemare analyzed. READ MORE

  6. 4. Performance Analysis of Cognitive Radio Networks with Interference Constraints

    Author : Hung Tran; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio Networks; Spectrum Underlay Access; Interference Constraints; Cognitive Cooperative Radio Networks;

    Abstract : To support the rapidly increasing number of mobile users and mobile multimedia services, and the related demands for bandwidth, wireless communication technology is facing a potentially scarcity of radio spectrum resources. However, spectrum measurement campaigns have shown that the shortage of radio spectrum is due to inefficient usage and inflexible spectrum allocation policies. READ MORE

  7. 5. Performance Analysis of Cognitive Radio Networks under Spectrum Sharing and Security Constraints

    Author : Louis Sibomana; Zepernick Hans-Jürgen; Slimane Ben Slimane; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underlay cognitive radio networks; spectrum sharing constraints; physical layer security;

    Abstract : The cognitive radio network (CRN) concept has been proposed as a solution to the growing demand and underutilization of the radio spectrum. To improve the radio spectrum utilization, CRN technology allows the coexistence of licensed and unlicensed systems over the same spectrum. READ MORE
