  • Communicating oceanographic research through film : the role of film in helping scientists develop and meet their broader impacts goals

    Creator:
    Madlener, Saskia D.
    Abstract:
    Funding agencies, specifically the National Science Foundation (NSF), are placing particular emphasis on the societal relevance and broader applications of scientific research, otherwise known as Broader Impacts (BIs). Scientists are required to address the BIs merit review criterion in their research proposals or they will not get funded. However, many...

  • Optimum equalization and synchronization of broadband multicarrier systems

    Creator:
    Lashkarian, Navid
    Abstract:
    The application of information theory and digital signal processing techniques to digital communication has resulted in robust methods for reliable high speed data transmission over noisy channels environments. Among these methods, multicarrier systems have become a viable solution for exploiting maximum spectral efficiency over both wideband highly dispersive static and...

  • Adaptive semi-soft handoff for cellular IP networks

    Creator:
    Nurvitadhi, Eriko
    Abstract:
    Rapid advances in wireless networking have led to more mobile phones, PDAs, and other digital mobile devices becoming ubiquitously connected to the Internet. As the demand of delay sensitive real-time applications for these portable devices increases, providing seamless connectivity to wireless networks becomes a critical issue. For this reason, a...

  • Ultra-Wideband Relay Communication Systems

    Creator:
    Abbasi, Arash
    Abstract:
    Impulse-radio ultra-wide-band (IR-UWB) signaling is a promising technique for high-speed, short-range relay communications networks. Depending on how the relay node retransmits the signal, there are two main relay schemes: conventional one-directional (one-way) relay model, and bi-directional (two-way) relay model. In bi-directional relay communications, wireless network coding (WNC), also called physical-layer...

  • A 2.4GHZ direct conversion mixer with offset cancellation

    Creator:
    Schmidbauer, Hardy
    Abstract:
    Dynamic DC offset is one of the biggest problems preventing the implementation of single chip receivers. This thesis presents a 2.4GHz downconversion mixer designed to work with adaptive DC offset cancellation for a fully integrated direct conversion receiver. Offset can be removed by dynamically changing the PFET load bias in...

  • Stretchable architectures for 3rd generation wireless networks

    Creator:
    Lakkavalli, Shashidhar V.
    Abstract:
    Power is a valuable resource. It is invaluable when for mobile devices. Mobile devices, due to their mobility cannot get a continuous source of power and derive their power from a battery contained in them. The main consumer of power in the mobile is its transmitter. With a limited power...

  • Conserving energy in TCP for mobile ad-hoc networks

    Creator:
    Agarwal, Sandeep, 1973-
    Abstract:
    The widespread use of TCP as a transport layer protocol for mobile ad-hoc networks and wireline networks has motivated the need to make its implementation highly power efficient specially with respect to ad hoc radio networks. Over the past years many researchers have developed energy efficient protocols for mobile ad-hoc...

  • LDPC-VBLAST for wireless communications

    Creator:
    Poocharoen, Panupat
    Abstract:
    Recently, the demand for higher data rates of transmission has increased in many wireless communication applications. Using multi-transmit and multi-receive antennas has been shown to be a solution, since it can increase the channel capacity to accommodate higher transmission rates. Among the popular techniques developed to exploit the use of...
