      The data rate requirements for future wireless systems has increased by orders-of-magnitude (from Kbps to several Mbps), requiring more sophisticated algorithms for their implementation. This tutorial will explore different ...
    • DSP Education At Rice University 

      Frantz, Patrick; Choi, Hyeokho; Baraniuk, Richard G. (2003-09-01)
      Rice University has a decades-long tradition of both digital signal processing (DSP) research and education, beginning in 1968. Since that time, Rice University has become a world leader and continued to be a pioneer in ...
    • A DSP-Based Platform for Wireless Video Compression 

      Murphy, Patrick; Bharadwaj, Vinay; Welsh, Erik; Frantz, Patrick (2002-11-01)
      With the exponential growth of wireless voice markets, demand for wireless video services is soon to follow. However, bandwidth limited wireless channels coupled with mobility issues pose a great challenge in the hardware, ...
    • Dual Problems in Power Control 

      Sabharwal, Ashutosh; Rajan, Dinesh; Aazhang, Behnaam (2001-10-20)
      In this paper, we study power control to minimize packet loss for delay-bounded transmission of bursty sources over Gaussian channels and transmission of constant rate sources over time-varying block fading channels. In ...
    • Dual Wi-Fi: Dual Channel Wi-Fi for Congested WLANs with Asymmetric Traffic Loads 

      Flores Miranda, Adriana (2013-10-08)
      In many WLANs scenarios, the load transmitted from the AP to the clients (Downlink), far outweighs traffic demand from the clients to the AP (Uplink), thereby yielding traffic asymmetry. Moreover, when many clients associate ...
    • Dual-frequency modulation and range disambiguation in laser rangefinding systems 

      Melton, Darren (1994)
      Laser rangefinders, which measure distances by detecting the phase shift of intensity modulated laser light reflected by objects, are very useful for obtaining 3-D models of the surrounding environment. A drawback of ...
    • The Dual-Tree Complex Wavelet Transform 

      Selesnick, Ivan W.; Baraniuk, Richard G.; Kingsbury, Nicholas G. (2005-11-01)
      The paper discusses the theory behind the dual-tree transform, shows how complex wavelets with good properties can be designed, and illustrates a range of applications in signal and image processing. The authors use the ...
