  • Partial network coding with cooperation : a study over multi-hop communications in wireless networks

    Creator:
    Poocharoen, Panupat
    Abstract:
    The imperfections of the propagation channel due to channel fading and the self-generated noise from the RF front-end of the receiver cause errors in the received signal in electronic communication systems. When network coding is applied, more errors occur because of error propagation due to the inexact decoding process. In...

  • Turbo-coded OCC-CDMA with spatial diversity for wireless mobile communications

    Creator:
    Tjahjadi, Aldo
    Abstract:
    Turbo codes have been used successfully for error correction in digital communications, however, their application to wireless mobile communications is still a fresh research topic. The objective of this thesis is to present a new solution that involves the usage of turbo codes, spatial diversity, and orthogonal complementary codes in...

  • A channelized digital receiver design for UWB sytems in a multipath indoor environment

    Creator:
    Chang, Yuhao
    Abstract:
    This thesis presents a channelized digital receiver design for UWB sytems in a multipath indoor environment. The UWB technology has been used for commercial and military purposes due to a number of advantages such as low-power consumption, noise-like and carrier free. The energy of UWB signal is spread over a...

  • Active robust control of cable-stayed bridges

    Creator:
    Scheer, Dietmar
    Abstract:
    Long bridges tend to develop large deformations under the action of intense dynamical loads such as wind or earthquakes. Unless these deformations are controlled in some fashion, the structure might suffer damage or even collapse. One possible solution to this problem is to apply external forces to the bridge through...

  • Fuzzy logic control of an inverted pendulum with vision feedback

    Creator:
    Holzapfel, Frank G.
    Abstract:
    Recent technical progress has made new forms of controller implementations on computers possible. Especially the technique of Fuzzy Logic Control has found a growing number of applications. Also the development of fast A/D converters has made the acquisation of data with vision based systems possible. In this project we combine...

  • Performance of MC-CDMA with pilot code and blind equalization algorithm

    Creator:
    Lesmana, Joseph Sam
    Abstract:
    Various methods and techniques have been introduced and applied to advance the state of the art of mobile wireless communications technology. For example, some techniques are applied to overcome the problem of multipath caused by the mobile environment. Multipath produces replicas of the wanted signal which arrive at the receiver...

  • A peer-to-peer communication system based on Walsh-Hadamard codes for fading environments

    Creator:
    Moranvil, William
    Abstract:
    High data rate transmission has become an important challenge in today digital communication systems. One of the most difficult problems faced by engineers is to transmit data at sufficiently high rates through fading channels. This is the main motivation for the research presented herein. In this thesis, we investigate a...

  • 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...

  • Adaptive broadband wireless interference mitigation architecture applying higher order statistics algorithm for computer platform

    Creator:
    Wang, Qiwei
    Abstract:
    The broadband wireless interference in a computer platform is resulted by multiple electro-magnetic emission sources. This non-Gaussian interference is proved to be double-sided K-distributed in previous research. With the limitation of transmission power and dimension of the device, interference mitigation is an efficient way to improve received signal bit error...
