  • Efficient content distribution on source constraint networks: peer communication

    Creator:
    Kamath, Rohit Vinodanand
    Abstract:
    Popular applications such as P2P file sharing, multiplayer gaming, videoconferencing, etc. rely on the efficiency of content distribution from a single source to multiple receivers. Most users of these applications are on the widely prevalent source constraint networks such as the Digital Subscriber Line (DSL) and wireless networks. Overlay multicast...

  • Non-data aided parametric based carrier frequency estimators for bursty GMSK communication systems

    Creator:
    Kandukuri, Ajay
    Abstract:
    Estimating the carrier frequency from a modulated waveform is one of the most important functions of a coherent signal receiver. Good performance and low bit error rates are obtained by coherent demodulation. Therefore, exact knowledge of the received signal carrier frequency is critical for communication systems. Also due to the...

  • Physical layer design of a robust low-power low-complexity optical wireless sensor system with angular diversity for metal-enclosed environments

    Creator:
    Trullinger, Von
    Abstract:
    The desire to apply short-range wireless communication systems to telemetry sensor networks in a metal-enclosed chamber has prompted this study. This thesis will discuss the design of an infrared (IR) communication system for a wireless low-power, low-data- rate sensor network in a metal enclosure. This design requires an in-depth understanding...

  • Tsunami Digital Library Needs Assessment: Final Report to Oregon State University Libraries and the Northwest Alliance for Computational Science & Engineering

    Creator:
    Lehman, Heather and Webster, Janet G.
    Abstract:
    The project team surveyed and interviewed forty identified experts within the diverse tsunami community. The survey revealed that this community is a sophisticated user of Internet search engines and tools and is very familiar with existing information. The sites mentioned most frequently as being helpful were those of the National...

  • Network coding for multi-user wireless networks

    Creator:
    Nguyen, Dong Van
    Abstract:
    Until a few years ago, wireless-capable laptops were considered novelties by many. It is now hard to find a laptop or a hand-held computing device that is not wireless-ready. As wireless devices are becoming commodities, they have also become an indispensable part of the modern society. Not surprisingly, research in...

  • A peer-to-peer communication system based on Walsh-Hadamard codes for fading environments

    Creator:
    Moranvil, William
    Abstract:
    High data rate transmission has become an important challenge in today digital communication systems. One of the most difficult problems faced by engineers is to transmit data at sufficiently high rates through fading channels. This is the main motivation for the research presented herein. In this thesis, we investigate a...

  • Interactive fault localization techniques to empower the debugging efforts of end-user programmers

    Creator:
    Ruthruff, Joseph Ronald
    Abstract:
    End users develop more software than any other group of programmers, using software authoring devices such as e-mail filtering editors, by-demonstration macro builders, and spreadsheet environments. Despite this, there has been only a little research on finding ways to help these programmers with the dependability of the software they create....

  • Fast algorithms and applications for multi-dimensional least-squares-based minimum variance spectral estimation

    Creator:
    Wei, Lin
    Abstract:
    The main contributions of this thesis are the development and application of four computationally efficient solutions for least-squares-based (LS-based) minimum variance spectral estimation (MVSE). They are: (1) fast computational solution for the 1-D covariance LS-based MVSE, (2) fast computational solution for the 1-D modified covariance LS-based MVSE, (3) fast computational...

  • Efficient VLSI architectures for MIMO and cryptography systems

    Creator:
    Li, Qingwei
    Abstract:
    Multiple-input multiple-output (MIMO) communication systems have recently been considered as one of the most significant technology breakthroughs for modern wireless communications, due to the higher spectral efficiency and improved link reliability. The sphere decoding algorithm (SDA) has been widely used for maximum likelihood (ML) detection in MIMO systems. It is...
