  • 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...

  • 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,...

  • 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...

  • 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...

  • 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....

  • A channelized digital receiver design for UWB sytems in a multipath indoor environment

    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...

  • 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...

    Abstract:
    Transmission over wireless networks presents multiple technical challenges due to noise, interference, fading, power constraints and bandwidth limitation. Different solutions have been propposed to overcome these issues and some of them are treated here. Cooperative diversity has been proposed as an implementation for networks where terminals are restricted to using...

    Abstract:
    In this paper, we propose a credit-based resource allocation technique for dynamic spectrum access (DSA) systems that is robust against malicious and selfi sh behaviors and ensures good overall system fairness performance while also allowing spectrum users to achieve high amounts of service. We also propose a new objective function...
