  1. 16. Performance Analysis and Implementationof Predictable Streaming Applications onMultiprocessor Systems-on-Chip

    Författare :Jun Zhu; Ingo Sander; Axel Jantsch; Shuvra Bhattacharyya; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Performance analysis; streaming applications; multprocessor; systems-on-chip; Information technology; Informationsteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Driven by the increasing capacity of integrated circuits, multiprocessorsystems-on-chip (MPSoCs) are widely used in modern consumer electron-ics devices. In this thesis, the performance analysis and implementationmethodologies are explored to design predictable streaming applications onMPSoCs computing platforms. LÄS MER

  3. 17. Performance Analysis of Cognitive Radio Networks with Interference Constraints

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

    Sammanfattning : 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. LÄS MER

  4. 18. Optimal Transmit Strategies for Multi-antenna Systems with Joint Sum and Per-antenna Power Constraints

    Författare :Le Phuong Cao; Tobias Oechtering; Skoglund Mikael; Martin Schubert; KTH; []
    Nyckelord :Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Nowadays, wireless communications have become an essential part of our daily life. During the last decade, both the number of users and their demands for wireless data have tremendously increased. Multi-antenna communication is a promising solution to meet this ever-growing traffic demands. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 20. Soft-Constrained Subband Beamforming for Speech Enhancement

    Författare :Zohra Yermeche; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : New speech acquisition applications are emerging as a result of advances in technology and the prevalence of mobile communication. While today voice control of consumer equipment is becoming a reality, communication technology has extended voice connectivity to personal computers and mobile communication devices with the aim of enabling natural communication in a variety of environments such as cars, restaurants and offices.
