    • Maximum Weight Basis Decoding of Convolutional Codes 

      Das, Suman; Erkip, Elza; Cavallaro, Joseph R.; Aazhang, Behnaam (2000-06-20)
      The effectiveness of the convolutional code increases with the constraint length of the code. Unfortunately the decoding complexity of Viterbi algorithm grows exponentially with the constraint length. In this paper we ...

      Das, Suman; Erkip, Elza; Cavallaro, Joseph R.; Aazhang, Behnaam (2002-11-01)
      In this paper we describe a new suboptimal decoding technique for linear codes based on the calculation of maximum weight basis of the code. The idea is based on estimating the maximum number locations in a codeword which ...
    • A Maxwell’s fish eye lens for the terahertz region 

      Liu, Jingbo; Mendis, Rajind; Mittleman, Daniel M. (2013-07-15)
      We implement a two-dimensional Maxwell’s fish eye lens using a waveguide-based artificial dielectric. The Maxwell’s fish eye lens consists of two metallic cylindrical plates sandwiching a free-space region, with the inner ...
    • Measurement driven deployment of a two-tier urban mesh access network 

      Camp, Joseph D. (2006)
      Multihop wireless mesh networks can provide Internet access over a wide area with minimal infrastructure expenditure. In this work, we investigate key issues involved in deploying such networks including individual link ...

    • Measurement of Filling-Factor-Dependent Magnetophonon Resonances in Graphene Using Raman Spectroscopy 

      Kim, Y.; Poumirol, J. M.; Lombardo, A.; Kalugin, N. G.; Georgiou, T.; Kim, Y. J.; Novoselov, K. S.; Ferrari, A. C.; Kono, J.; Kashuba, O.; Fal’ko, V. I.; Smirnov, D. (2013-05-29)
      We perform polarization-resolved Raman spectroscopy on graphene in magnetic fields up to 45 T. This reveals a filling-factor-dependent, multicomponent anticrossing structure of the Raman G peak, resulting from magnetophonon ...
    • Measurement-based admission control in integrated-services networks 

      Qiu, Jingyu (1998)
      To satisfy the quality of service requirements of real-time multimedia applications, networks must employ resource reservation and admission control. In this paper, we describe a new Measurement-Based Admission Control ...
    • Measurements vs. Bits: Compressed Sensing meets Information Theory 

      Sarvotham, Shriram; Baron, Dror; Baraniuk, Richard G. (2006-09-01)
      Compressed sensing is a new framework for acquiring sparse signals based on the revelation that a small number of linear projections (measurements) of the signal contain enough information for its reconstruction. The ...
