  • A simple RLS-POCS solution for reduced complexity ADSL impulse shortening

    Creator:
    Helms, Sheldon J.
    Abstract:
    Recently, with the realization of the World Wide Web, the tremendous need for high-speed data communications has grown. Several access techniques have been proposed which utilize the existing copper twisted pair cabling. Of these, the xDSL family, particularly ADSL and VDSL, have shown great promise in providing broadband or near-broadband...

  • Content-based color image retrieval

    Creator:
    Varanguien de Villepin, Audrey
    Abstract:
    A fully automated method for content-based color image retrieval is developed to extract color and shape content of an image. A color segmentation algorithm based on the k-mean clustering algorithm is used and a saturated distance is proposed to discriminate between two color points in the HSV color space. The...

  • Design and Implementation of a Wearable Walking Navigation Assistance System for the Vision Impaired

    Creator:
    Sylwester, Sean T.
    Abstract:
    Few navigation-assistance technologies for vision impaired individuals are practical due to inhibiting factors such as cost, comfort, convenience, and overall usefulness of the assistance. This thesis will present the design and implementation of a navigation assistance system intended to address these concerns. The presented system improves on existing technologies by...

  • Power efficient analog-to-digital converters using both voltage and time domain information

    Creator:
    Oh, Taehwan
    Abstract:
    As advanced wired and wireless communication systems attempt to achieve higher performance, the demand for high resolution and wide signal bandwidth in their associated ADCs is strongly increased. Recently, time-domain quantization has drawn attention from its scalability in deep submicron CMOS processes. Furthermore, there are several interesting aspects of time-domain...

  • Efficient decoder design for error correction codes

    Creator:
    He, Jinjin
    Abstract:
    Error correction codes (ECCs) have been widely used in communication systems and storage devices. Nowadays, the rapid development of integrated circuit technologies makes feasible the implementation of powerful ECCs such as turbo code and low-density parity-check (LDPC) code. However, these high-performance codes require complex decoding algorithms, resulting in large hardware...

  • A VHDL description of speech recognition front-end

    Creator:
    Xiao, Xin
    Abstract:
    This thesis investigates an implementation of speech recognition front-end. It is an application specific integrated circuit (ASIC) solution. A Mel Cepstrum algorithm is implemented for the feature extraction. We present a new mixed split-radix and radix-2 Fast Fourier Transform (FFT) algorithm, which can effectively minimize the number of complex multiplications...

  • End user software engineering features for both genders

    Creator:
    Sorte, Shraddha
    Abstract:
    Previous research has revealed gender differences that impact females’ willingness to adopt software features in end users’ programming environments. Since these features have separately been shown to help end users problem solve, it is important to female end users’ productivity that we find ways to make these features more acceptable...

  • Interpolation-based digital quadrature frequency synthesizer

    Creator:
    Larson, Ryan John
    Abstract:
    Traditionally sinusoidal signal generation has been implemented with purely analog circuits such as phase-locked loops. The alternative of using a digital system to perform this signal generation has previously been unattractive due to limitations in clock frequency and size. However, recent advancements in sub-micron fabrication techniques have made the digital...

  • OptoNet- a non-directional infrared communication link for local area networks

    Creator:
    Liu, Dongtai
    Abstract:
    This thesis work researches the theory and application of systems performing omnidirectional, non-direct path optical data communication (ONP systems). Such systems are characterized by 1) the communication involves a local, usually circular area; 2) Obstacles are allowed between a transmitter and the receivers. This is in contrast to the point-to-point...

  • Implementation of Distributed Localized Communications

    Creator:
    Snyder, Thomas
    Abstract:
    Artificial collectives are useful for accomplishing tasks that require teamwork from multiple simple robots. Multiple robot and collective testbeds have been developed, yet none stay committed to leverage the local interactions, group size, and imperfect information assumptions that strengthen biological collectives. A review of the collective and multiple robot literature,...
