  • Sensor communication network within a desktop computer using the DC powerline

    Creator:
    Bahniuk, Eileen Kei
    Abstract:
    Powerline communication (PLC), is becoming a more commonplace method for data transmission, however it is still a very new medium for data transmission, and international standards for powerline communication are still in the process of being developed and established. PLC can provide a means of simplifying the device connectivity to...

  • Hybrid AOA and TDOA Solution for Transmitter Positioning

    Creator:
    Ahmed, Sarah A.
    Abstract:
    Accurate positioning has become an active research area in recent years. It has a wide range of applications in many fields such as navigation, asset tracking, health care, proximity marketing/location-based advertising, and sport analytics. Transmitter positioning via radio frequency (RF) signals is the most widely encountered scenario, and it uses...

  • An Anthology of Next-Generation WSNs and Transformative IoT Use-Cases

    Creator:
    Williams, Jennifer M.
    Abstract:
    The Internet of Things (IoT) paradigm brought an ever-increasing dependence on low-power devices to collect sensor data and transmit that information to the cloud, placing greater demand on connectivity and lifespan. In response, rapid worldwide innovation demonstrates the trade-offs in processing, communication, and energy consumption with diverse approaches to low-power...

  • Exploring Indoor Navigation Based on 9-dof Kalman Filter and SLAM Algorithm

    Creator:
    Qin, Shuxian
    Abstract:
    Traditional localization techniques rely on triangulation or trilateration, where in a set of three or more stationary known locations is used to estimate a “client” position. For inertial navigation, these techniques can estimate client positions merely using the measured data from tri-axial accelerometers and gyroscopes. However, the use of double...

  • 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...

  • Channel estimation and data detection for mobile MIMO OFDM systems

    Creator:
    Gao, Jie
    Abstract:
    Designing spectral efficient, high-speed wireless links that offer high quality- of-service and range capability has been a critical research and engineering challenge. In this thesis, we mainly address the complexity and performance issues of channel estimation and data detection in multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems over...

  • Pulsed ultra-wideband: transmission, detection, and performance

    Creator:
    Zhao, Shiwei
    Abstract:
    Ultra-wideband (UWB) communication has emerged as a very promising technology for short-range wireless applications, including high-speed multimedia transmissions and sensor networks. UWB system designs involve many different aspects covering analog and digital processing, channel estimation and modeling, and modulation and demodulation. Although UWB still faces many challenges, significant progress has...

  • Ultra-wideband indoor localization systems

    Creator:
    Ye, Ruiqing
    Abstract:
    Indoor localization systems have a variety of applications such as tracking of assets, indoor robot navigation, and monitoring of people (e.g. patients) in hospitals or at home. Global positioning system (GPS) offers location accuracy of several meters and is mainly used for outdoor location-based applications as its accuracy degrades significantly...

  • Position estimation in indoor localization system

    Creator:
    Qiao, Tianzhu
    Abstract:
    Indoor positioning systems can be used for many applications such as indoor navigation,emergence response, asset monitoring, and shopper assistance. Due to the weak received signal and multipath reflection, the global positioning system (GPS) generally does not work in indoor environments. There are a variety of radio frequency (RF) signals and...

  • Security protocols for linear network coding

    Creator:
    Adeli, Majid
    Abstract:
    Network coding, as the next generation of data routing protocols, enables each intermediate node in a network to process and encode its received data before forwarding it to the next nodes. Hence, the core idea in network coding is to allow a network to encode the data that is being...
