  • 802.11b Operating in a Mobile Channel: Performance and Challenges 

    Steger, Christopher; Radosavljevic, Predrag; Frantz, Patrick (2003-09-20)
    In the past, the worlds of wireless voice and data transmission have been largely disjoint. Voice traffic has been carried over circuit-switched cellular links, and data has been largely restricted to packet-switched ...
  • Modeling of Welkin RF in a DSSS System 

    Guo, Yuanbin (2000-09-20)
    In this report, the author studied the methodology of distortion-true software modeling for RF (radio frequency) in a DSSS W-CDMA system. A complete end-to-end testbed based on the Welkin RF system is built by SystemView ...
  • Preamble-based Symbol Timing Estimation for Wireless OFDM Systems 

    Gadhiok, Manik; Cavallaro, Joseph R. (2007)
    We propose a timing estimation scheme that reduces computational complexity while achieving performance comparable to the autocorrelation method commonly employed at the wireless receiver. The proposed method is based ...
