  • Adaptive digital linearization of RF power amplifiers

    Publication Year: 1995, Page(s):65 - 71

    The performance of an adaptive digital technique for the linearization of RF power amplifiers is investigated. Cubic spline interpolation is used to estimate the amplifier's AM-AM and AM-PM characteristics. Using the computed characteristic coefficients, the baseband input signal is appropriately predistorted to compensate for the amplifier nonlinearity. This method has significantly better suppre...

  • VLSI array processors for linear-phase FIR filters

    Array processor implementations are obtained for linear-phase FIR filters. Three structures are reported in which the inputs are pipelined and/or broadcast and the outputs are pipelined. A novel structure is obtained in which the outputs are localized in separate processing elements. A comparison among the resulting structures is performed based on the processing rate, the latency, and the communi... View full abstract»

  • Optimized DC motor output in a photovoltaic system

    Publication Year: 1995, Page(s):78 - 84

    Dc motor drives normally operate from independent sources. Speed-control strategies are based on the premise of a constant-voltage source. A photovoltaic array provides a nonconstant voltage, especially if maximum power point tracking is employed to optimize the return of a high capital-cost investment. This situation requires different control strategies to adjust the motor's characteristics, bot... View full abstract»

  • Modelling the interaction of multiple small harmonic current sources in an isolated power distribution system

    Publication Year: 1995, Page(s):85 - 90
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5731 KB)

    Given the growing number of interactive nonlinear loads in power distribution systems, some techniques to monitor the spread of harmonics through the system need to be developed. This paper examines the nature of harmonics in a naval power distribution system and develops a harmonic model using the CYMHARMO package to monitor current sources and the interaction that can occur in the Canadian Patro...

  • Classifying cereal grains using backpropagation and cascade correlation networks

    Publication Year: 1995, Page(s):91 - 94

    This paper presents backpropagation- and cascade correlation-trained artificial neural networks for cereal grain classification. In comparison with a Gaussian classification technique, the neural networks deliver higher classification accuracy and are more attractive for implementation in automated grain inspection systems.
