  • 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...

  • Data rate improvements for the IEEE 802.11 wireless local area network standard through the use of code division multiple access and turbo coding

    Creator:
    Buck, David H.
    Abstract:
    The widespread use of Wireless Local Area Networks (WLAN) and the desire for such products from different vendors to operate together has generated a movement towards standardization. Over the last decade, several organizations worldwide have researched and developed such standards, this includes the IEEE 802.11 committee. One of the important...

  • 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...

  • Application of WiMAX to aviation communications

    Creator:
    Kim, Sang Jun
    Abstract:
    The US military is evaluating the capabilities of emerging technologies based on IEEE 802.16 standard as a potential commercial off-the-shelf solution to support the communication requirements of the future war. In the last few years, development in military and telecommunication industries have focused on an intensive use of broadband systems,...

  • Feedback in multiple antenna wireless communication systems

    Creator:
    Xu, Tao
    Abstract:
    Multiple-input multiple-output wireless systems promise significant capacity gain and/or diversity gain over single antenna systems. If channel state information (CSI) is available at both the transmitter and the receiver, the performance can be further improved. In this thesis, first, we study binary index feedback problem in beamforming systems when the...

  • PAPR Reduction of Optical OFDM Systems with Exponential Companding Transform and Zero Padding

    Creator:
    Chen, Deyan
    Abstract:
    Optical wireless communication (OWC) is an alternative to radio frequency (RF)communication with a signi cantly larger and unregulated spectrum. In OWC systems, optical orthogonal frequency division multiplexing (O-OFDM) with intensity modulation and direct detection (IM/DD) is commonly used. There are two common signal structures in most OWC systems based on...

  • 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...

  • Network coding in relay networks

    Creator:
    Alban, Eduardo
    Abstract:
    Transmission over wireless networks presents multiple technical challenges due to noise, interference, fading, power constraints and bandwidth limitation. Different solutions have been propposed to overcome these issues and some of them are treated here. Cooperative diversity has been proposed as an implementation for networks where terminals are restricted to using...
