  • Diversity combining ARQ over the m(> 2)-ary unidirectional channel

    Creator:
    Elarief, Noha
    Abstract:
    In diversity combining automatic repeat request (ARQ), erroneous packets are combined together forming a single, more reliable, packet. In this thesis, we give a diversity combining scheme for the m-ary unidirectional channel. A system using the given scheme with a t-unidirectional error detecting code is able to correct up to...

  • Redundant information in a spin system beyond pure decoherence

    Creator:
    Svesko, Andrew M.
    Abstract:
    Quantum physics in the Copenhagen interpretation places an unsatisfying divide between the quantum and classical worlds. Decoherence -- the destruction of superposition states of the system -- helps us understand how the quantum transitions to the classical. Quantum Darwinism builds on decoherence to understand how information about the system is...

  • On edge disjoint Hamiltonian cycles in torus and Gaussian networks

    Creator:
    Alazemi, Fawaz M.
    Abstract:
    Many algorithms in parallel systems can be easily solved if we can generate a Hamiltonian cycle on the underly network. Finding Hamiltonian cycle is a well known NP-complete problem. For specific instances of regular graphs, such as Torus and Gaussian network, one can easily find Hamiltonian cycles. In this thesis,...

  • Power reduction of MPEG video decoding for mobile multimedia systems

    Creator:
    Lewis, James M.
    Abstract:
    The purpose of this thesis is to explore methods which can reduce the power dissipation of a mobile system while decoding MPEG video. MPEG decoding is a microprocessor intensive process that makes heavy use of both the L1 and L2 caches as well as main memory. The heavy load placed...

  • Adaptive broadband wireless interference mitigation architecture applying higher order statistics algorithm for computer platform

    Creator:
    Wang, Qiwei
    Abstract:
    The broadband wireless interference in a computer platform is resulted by multiple electro-magnetic emission sources. This non-Gaussian interference is proved to be double-sided K-distributed in previous research. With the limitation of transmission power and dimension of the device, interference mitigation is an efficient way to improve received signal bit error...

  • A statistical inference framework for finding recurring patterns in large data with applications to energy management

    Creator:
    You, Zeyu
    Abstract:
    We consider the problem of finding unknown patterns that are recurring across multiple sets. For example, finding multiple objects that are present in multiple images or a short DNA code that is repeated across multiple DNA sequences. We first consider a simple problem of finding a single unknown pattern in...

  • Compensation method of the excess loop delay in continuous-time delta-sigma ADCs based on model matching approach

    Creator:
    Guo, Jia
    Abstract:
    Continues-Time (CT) Delta-Sigma (ΔΣ) Analog-to-Digital Converters (ADCs) have one important constrain, namely the excess loop delay. Most previous excess lop delay compensation methods need to know the exact value of the excess loop delay in advance. However, the value of the excess loop delay is a uniformly distribution random variable....

  • Measurement and characterization of ultra-wideband wireless interconnects within active computing systems

    Creator:
    Woracheewan, Sirikarn
    Abstract:
    Ultra-wideband (UWB) radio has become an attractive alternative for wireless communications due to the robustness to multipath fading, low power transmission, mostly-digital implementation, and low cost. Furthermore, short-range, high data-rates applications are possible with UWB radios due to the wide spectral allocations at 3.1 - 10.6 GHz. This thesis presents...

  • Quality assessment strategies for multi-camera panorama video

    Creator:
    Leorin, Simone
    Abstract:
    New video-conference devices based on omnidirectional multi-camera systems have been emerging in the last few years. These devices require innovative and automated video quality assessment in the earlier stages of their design in order to guarantee competitive product development and quality monitoring. Current quality assessment techniques are not adequate since...

    Creator:
    Chang, Yuhao
    Abstract:
    This thesis presents a channelized digital receiver design for UWB sytems in a multipath indoor environment. The UWB technology has been used for commercial and military purposes due to a number of advantages such as low-power consumption, noise-like and carrier free. The energy of UWB signal is spread over a...
