    Recently, we proposed a low-cost adaptive algorithm for noise (or minor) subspace estimation based on the generalized Rayleigh's quotient. In this paper, we show how to numerically stabilize this algorithm using Householder transformation without incurring any significant increase in its computational complexity. Simulation results are given to validate this new algorithm View full abstract»

    In this paper, we propose and analyze the wavelet transform-domain LMS (WTDLMS) algorithm where only a subset of the adaptive filter coefficients are updated at each iteration. The use of wavelets or subband filterbanks can lead to several novel schemes whose combinations can lead to other sub-schemes as well. In the proposed scheme, the coefficients can be selected altogether as a block and not j... View full abstract»

  • A transmitter architecture for nonconstant envelope modulation

    This paper presents a transmitter architecture which is less sensitive to power amplifier AM/AM and AM/PM conversions. Indeed, most radio communication standards employ nonconstant envelope modulation such as in the 802.11 series. Owing to power amplifiers' nonlinearities, distortions on the modulations degrade the overall transmitter performance. As a consequence, linearization methods, such as e... View full abstract»

    This paper presents a new topology for a current-mode Wheatstone bridge (CMWB) that uses an operational floating current conveyor (OFCC) as a basic building block. The proposed CMWB has been analyzed, simulated, implemented, and experimentally tested. The experimental results verify that the proposed CMWB outperforms existing CMWBs in terms of accuracy. A new CMWB linearization technique based on ... View full abstract»

    A closed-form expression for computing the exact Cramer-Rao lower bound (CRLB) on unbiased estimates of the parameters of a two-dimensional (2-D) autoregressive moving average (ARMA) model is developed. The formulation is based on a matrix representation of 2-D homogeneous Gaussian random process that is generated uniformly from the related 2-D ARMA model. The formulas derived for the exact Fisher... View full abstract»

  • Global synchronization and asymptotic stability of complex dynamical networks

    Global synchronization and asymptotic stability of complex dynamical networks are investigated in this paper. Based on a reference state, a sufficient condition for global synchronization and stability is derived. Unlike other approaches where only local results were obtained, the complex network is not linearized in this paper. Instead, the sufficient condition for the global synchronization and ...

  • A new design topology for low-voltage CMOS current feedback amplifiers

    A new topology for designing low-voltage current feedback amplifiers (CFAs) is presented. By employing a second-generation positive current conveyor followed by an operational amplifier in an unconventional manner, the design circumvents the problem of trying to achieve large transimpedance in a low-voltage environment. It is shown that this CFA configuration also results in near gain independent ... View full abstract»

    Repetitive processes are a distinct class of two-dimensional (2-D) systems (i.e., information propagation in two independent directions) of both systems theoretic and applications interest. They cannot be controlled by direct extension of existing techniques from either standard [termed one-dimensional (1-D) here] or 2-D systems theory. Here, we give new results on the relatively open problem of t... View full abstract»

  • Nonlinear feedback control of chaos in permanent magnet synchronous motor

    Permanent magnet synchronous motor (PMSM) will demonstrate chaotic phenomena when its parameters fall into a certain area. The performance of PMSM will degrade because of chaos. Therefore, chaos should be suppressed or eliminated. According to the features of this practical plant, the drawbacks of existing control methods are analyzed, and the nonlinear feedback control method is suggested to cont... View full abstract»

    In this brief, we introduce a subspace theory for differential chaos-shift keying (DCSK) systems. We show that DCSK systems operate by transmission of chaotic signals residing in a low-dimensional subspace. The subspace formalism of DCSK schemes leads to the derivation of useful subspace detectors that can be applied to decode the DCSK signal for various types of channels. Closed form expressions ...

  • Design and analysis of an optimal controller for parallel multi-inverter systems

    Optimal control methodology is applied to the design of the feedback loops of a multi-inverter uninterruptible power supplies system. The control signals thus obtained will minimize a performance index, which is a function of the output voltage error, the inductor currents of all inverters and the reference signals. This enables the controller to achieve the desired objectives like minimization of... View full abstract»

    In this paper, we propose a new spatial temporal predictor using support vector machine (SVM) and data fusion technique. SVMs are used as temporal predictors at different spatial domains and spatial temporal prediction is achieved by prediction fusion. Our proposed prediction fusion technique improves the prediction accuracy even in a non-Gaussian environment. The performance of the proposed spati... View full abstract»

    A novel noise-shaping feedback coding scheme is derived by bounding and minimizing its filtered reconstruction error. The stability and performance of this coding scheme are rigorously analyzed. Analytic designs then can be obtained based on the derived stability conditions and noise-shaping equation. A fifth-order coder is designed for converting 3 MHz wide-band signal to a 4-bit quantized signal... View full abstract»

    A novel analytical procedure for the tuning of finite-impulse response (FIR) filters is introduced. The tuning procedure adjusts a single frequency of the frequency response to the desired value while preserving the nature of the filter. The impulse responses of the original and of the final filter are related by the transformation matrix. Two examples in the analytical design of notch FIR filters... View full abstract»
