  • Robust Slope Region for Wideband CDMA With Multiple Antennas 

    Muharemovic, Tarik; Aazhang, Behnaam (2003-04-01)
    We analyze a low power, wideband CDMA system with multiple antennas. The joint "slope region" - of transmission rates at minimum energy per bit - is derived as a function of proportion between vanishing rates for multiple ...
  • Robust Solution of the Linear Servomechanism Problem 

    Staats, P.W.; Pearson, J.B. (1974-09-01)
    This paper furnishes a complete solution to the problem of designing robust controllers for linear servomechanisms. The results complete the work begun in [1] in that arbirary exogenous signals are included in the problem ...
  • Robustness in Parameter Estimation 

    Papantoni-Kazakos, P. (1975-10-20)
    Due to vagueness in the definition of robustness, there has been no natural transition between robust and nonparametric parameter estimators. In this work, qualitative ideas first expressed by Hampel [1] are extended in ...

    Hughes, Christopher J.; Pai, Vijay S.; Ranganathan, Parthasarathy; Adve, Sarita V. (2002-02-20)
    Rsim is a publicly available architecture simulator for shared-memory systems built from processors that aggressively exploit instruction-level parallelism. Modeling ILP features in a multiprocessor is particularly important ...
  • Safety of Robotic Systems - Guest Editorial 

    Petersen, Kurt E.; Walker, Ian D.; Cavallaro, Joseph R. (1996-09-01)
    We were delighted to be invited by the editors of Reliability Engineering and System Safety to organise a special issue on the Safety of Robotic Systems. Robotic systems have now reached a level of sophistication far ...
  • Sampling and recovery of pulse streams 

    Hegde, Chinmay (2010)
    Compressive Sensing (CS) is a new technique for the efficient acquisition of signals, images, and other data that have a sparse representation in some basis, frame, or dictionary. By sparse we mean that the N -dimensional ...
  • Scalable and Low Power LDPC Decoder Design Using High Level Algorithmic Synthesis 

    Sun, Yang; Cavallaro, Joseph R.; Ly, Tai (2009-09-01)
    This paper presents a scalable and low power low-density parity-check (LDPC) decoder design for the next generation wireless handset SoC. The methodology is based on high level synthesis: PICO (program-in chip-out) tool ...
