  • A signal-processed antenna system and the simulation of the effects of balanced-mixer frequency conversion

    Creator:
    Spencer, Kenneth Edward
    Abstract:
    In this paper a signal-processed antenna and receiver system is proposed and analyzed. In addition, a simulation of the balanced-mixer portion of the processing system is made on a hybrid computer to find the bandwidth limitations for the total system. The system utilizes both the amplitude and phase information of...

  • 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...

  • Multiple antenna techniques for pulse-based ultra-wideband system

    Creator:
    Vemulapalli, Sudheer
    Abstract:
    fIndoor wireless local area networks (LAN's) and personal area networks (PAN’s) have evolved very rapidly in the recent past. The indoor wireless LAN's are mainly dominated by narrow-band technologies like the IEEE 802.11a,b which are short range and provide data rates of 1 Mbps to 54 Mbps. The Bluetooth has...
