  4. 2. On Modulation and Detection Schemes for Low-Complexity Impulse Radio UWB Communications

    Author : Muhammad Gufran Khan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UWB; RAKE; Transmitted reference; Energy detection; Channel measurements; BPPM;

    Abstract : Due to wealth of advantages offered by short range ultra wideband (UWB) technology, such as capacity improvement, fading reduction and localization, it has gathered a considerable attention. Distinct UWB qualities also pose many system design challenges like difficulties in using digital processing, complex channel estimation and different propagation characteristics. READ MORE

    Abstract : Parametric signal models are used in a multitude of signal processing applications. This thesis deals with signals for which there are many candidate models, and it is not a priori known which model is the most appropriate one. READ MORE

  6. 4. On Coherent and Non-coherent Receiver Structures for Impulse Radio UWB Systems

    Author : Muhammad Gufran Khan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The demand and growth of short-range wireless communications has been tremendous in the past few years for a diverse range of applications. There is significant interest in ultra wideband (UWB) as a physical layer technology for both high-data-rate (HDR), and low power, low-data-rate (LDR) short-range communications. READ MORE

  7. 5. On the Physical Layer of Ultra-Wideband Systems

    Author : Matts-Ola Wessman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This licentiate thesis consists of two published conference papers, onetechnical report, and an introduction. The focus is on communication at bitrates of 100 Mbps and higher for single-user systems at short range up to 10meters. READ MORE
