    In this paper we present a novel heuristic for improving the variable order computation in the binary decision diagram. The proposed algorithm uses two way swapping and it oscillates forward and backward to minimize the number of cycles needed to get the best order. The validity of the proposed approach has been shown using ISCAS 85 benchmarks View full abstract»

  • Neural network modeling of land mobile radio channels with nonlinear transmit amplifiers

    Publication Year: 2000, Page(s):954 - 957 vol.2
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (260 KB)

    Mobile radio transmission is characterized by the use of a high-power amplifier due to severe channel fading. In addition, it is a nonstationary transmission because of the time-varying channel, since the transmitter is a mobile user. Neuronal systems present the advantage of being nonlinear and have a good ability for apprenticeship. That justifies the approach of neuronal modeling that we propos... View full abstract»
