  • Real Time Self-Interference Cancellation for Wireless Transceivers

    Creator:
    Taylor, Daniel N.
    Abstract:
    With the need for higher spectral efficiency and data rates the rise of simultaneous transmit-and-receive (STAR) radios is becoming increasingly valuable. While many systems employ two separate channels for transmit and receive to double the data speed, this comes at the cost of doubling the RF band. This same performance...

  • Demonstration of Indoor Localization of Miniature Objects Using Wireless-PoweredUltra-Wideband Tags

    Creator:
    Su, Leon
    Abstract:
    Wireless localization of objects is useful for several applications that require the knowledge of position of objects or people. Additionally, power extraction from wireless signals eliminates the need for wires or any physical connections for charging. This project is based on system-level testing of an integrated circuit (IC) that combines...

  • Design and Analysis of an Optical Wireless Receiver for a Hybrid WiFi Free-Space Optical (WiFO) Communication Network

    Creator:
    Borah, Anindita
    Abstract:
    The increasing demand for higher data-rates in spectrum-deficient indoor WiFi networks calls for the adaptation of hybrid systems, consisting of RF and optical wireless channels. The novel hybrid WiFi Free-Space Optical (WIFO) system was introduced to enhance the wireless capacity of indoor WiFi networks. In this thesis, an optical wireless...

  • Co-channel Blocker and Self-Interferer Tolerant Receiver Architectures for MIMO and Full-Duplex MIMO Receivers

    Creator:
    Jain, Sanket
    Abstract:
    This research focuses on receiver architectures which enable better spectral eciency by handling blockers in the same spectral range as the signal. The presence of such blockers, without the use of blocker cancelling/ ltering techniques leads to gain compression and hence, consequent performance degradation of receivers leading to reduced spectrum...
