    • 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 ...
    • A FPGA­Based Experimental PHY for 802.11b WLAN 

      Lou, Feifei; Murphy, Patrick; Frantz, Patrick (2003-10-20)
      The swift proliferation of wireless data communication systems, and the ever-increasing demand for faster data rates requires that engineers be able to quickly design, implement and test new wireless algorithms for data ...
    • 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 ...

    • Protocol Design and Experimental Evaluation for Efficient Multi-User MIMO Wireless Networks 

      Bejarano Chavez, Oscar (2015-04-24)
      Information theoretic results on Multi-User MIMO (MU-MIMO) have demonstrated a many-fold increase in capacity compared to Single-Input Single-Output. By leveraging multiple antennas at the Access Point (AP) and beamforming ...
