  • Threshold Selection Based on the SNR in Time of Arrival Localization System

    Creator:
    Lyu, Tao
    Abstract:
    Threshold-based time of arrival (TOA) estimation is a technique for high-precision indoor localization. Existing threshold selection methods, such as xed thresh- old and normalized threshold methods, do not consider the signal-to-noise radio (SNR) value at the receiver. This is not desired for high-precision positioning. A proper threshold value depends on...

  • Design and FPGA implementation of digital transmission over severe ISI channels

    Creator:
    Zhao, Yichen
    Abstract:
    Inter-symbol interference is one of the major factors that make the realization of high-data-rate digital communications system complex. Current designs face two main challenges: how to efficiently utilize the available bandwidth and how to reduce the hardware complexity of the transmitter and receiver. Traditional solutions use a single-band architecture. When...

  • Performance and optimization of pulsed UWB localization with large number of sources

    Creator:
    Kwon, Changho
    Abstract:
    Pulsed ultra-wideband (UWB) radio uses extremely short pulses to transmit information. Such pulses provide very fine timing information, which has led to technological advances in high-precision localization. This thesis focuses on techniques and experiments of Time-Difference-of-Arrival (TDOA) localization of a large number of simultaneous sources. First, common localization techniques such...

  • Position estimation in indoor localization with trilateration

    Creator:
    Su, Zhenqiang
    Abstract:
    Triangulateration uses geometric distance to estimate the location of user by employing techniques like received signal strength (RSS), time-of-arrival (TOA), time-difference-of-arrival (TDOA) and image processing. Radio frequency (RF) signal positioning using TOA or TDOA techniques generally requires timing synchronization of the anchors and/or the anchors and targets. If the desired...
