    • Distributed Multiscale Data Analysis and Processing for Sensor Networks 

      Wagner, Raymond; Sarvotham, Shriram; Choi, Hyeokho; Baraniuk, Richard G. (2005-02-01)
      While multiresolution data analysis, processing, and compression hold considerable promise for sensor network applications, progress has been confounded by two factors. First, typical sensor data are irregularly spaced, ...
    • Distributed partial decoding in cooperative communication systems 

      Karkooti, Marjan (2009)
      Increasing demand for wireless services is putting major pressure on network resources, which demands a new paradigm with a more efficient design. Recently, cooperative communications has emerged as a viable option for ...
    • Distributed Protocols for Signal-Scale Cooperation 

      Hunter, Christopher R. (2012)
      Signal-scale cooperation is a class of techniques designed to harness the same gains offered by multi-antenna communication in scenarios where devices are too small to contain an array of antennas. While the potential ...
    • Distributed redundant representations in man-made and biological sensing systems 

      Rozell, Christopher John (2007)
      The ability of a man-made or biological system to understand its environment is limited by the methods used to process sensory information. In particular, the data representation is often a critical component of such ...
    • Distributed Resource Allocation with Local Information 

      Dash, Debashis (2013-12-09)
      Making distributed decisions based on incomplete information is inevitable in dynamic wireless networks due to a multitude of constraints. We study the effects of incomplete information on system performance in two parts. ...
    • Distributed scheduling and multi-channel opportunistic media access for ad hoc networks 

      Kanodia, Vikram (2004)
      Current wireless ad hoc networks suffer from two main performance limitations. First, current ad hoc networks do not efficiently utilize the scarce and dynamic wireless spectrum. As a result, the goodput of current ad hoc ...
    • Distributed Wavelet Transform for Irregular Sensor Network Grids 

      Wagner, Raymond; Choi, Hyeokho; Baraniuk, Richard G.; Delouille, Veronique (2005-07-01)
      Wavelet-based distributed data processing holds much promise for sensor networks; however, irregular sensor node placement precludes the direct application of standard wavelet techniques. In this paper, we develop a new ...
    • Diverging moments and parameter estimation 

      Goncalves, Paulo; Riedi, Rudolf H. (2004-01-15)
      Heavy tailed distributions enjoy increased popularity and become more readily applicable as the arsenal of analytical and numerical tools grows. They play key roles in modeling approaches in networking, finance, hydrology ...
    • DOMAIN WALL VELOCITY IN MAGNETIC MATERIALS 

      BARTRAN, DAVID SAMUEL, JR. (1973)
    • DSP architectural considerations for optimal baseband processing 

      Rajagopal, Sridhar; Rixner, Scott; Cavallaro, Joseph R.; Aazhang, Behnaam (2002-08-20)
      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 ...
