  3. 2. Multiantenna Cellular Communications : Channel Estimation, Feedback, and Resource Allocation

    Författare :Emil Björnson; Björn Ottersten; Mats Bengtsson; Marios Kountouris; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel estimation; limited feedback; multicell communications; resource allocation;

    Sammanfattning : The use of multiple antennas at base stations and user devices is a key component in the design of cellular communication systems that can meet the capacity demands of tomorrow. The downlink transmission from base stations to users is particularly limiting, both from a theoretical and a practical perspective, since user devices should be simple and power-efficient, and because many applications primarily create downlink traffic (e.

  4. 3. Managing Collaborative Product Development : A Model for Identifying Key Factors in Product Development Projects

    Författare :Sofi Elfving; Mats Jackson; Björn Fagerström; Lars Bengtsson; Mälardalens högskola; []
    Nyckelord :Collaborative product development; Integrated product development; Concurrent engineering; Product development; Product design; Collaboration; Integration; Communication; Key factors; Decision-making; Knowledge transfer; Experience reuse; TECHNOLOGY; TEKNIKVETENSKAP; Innovation och design;

    Sammanfattning : The increasing complexity of products and systems today has forced new processes, methods, and tools for managing the development of products. It has also forced the development of complex organisations and diverse relationships among functions and peoples within product development organisations. This implies a need for integrated processes. LÄS MER

  5. 4. Positioning Biopsy Needles in the Prostate Gland Using 3D Computer Modelling

    Författare :Hans Frimmel; Ewert Bengtsson; Björn Gudmundsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computerized Image Analysis; Datoriserad bildanalys;

    Sammanfattning : In the world of medicine, image diagnostics have, until recently, been based merely on two dimensional information sources. The understanding of three dimensional structures has been limited to creating mental images in the mind of the physician, to wax models and to autopsy. LÄS MER

  7. 5. Transmission Optimization for High Throughput Satellite Systems
