    The aim of this paper is to present a solution to the problem of induction machines rotor flux reconstruction and rotor resistance estimation by using a sliding mode observer based on singular perturbation theory. This approach allows the decomposition of the original model, described in two-time-scales, into two reduced-order models. Based on simulations, this study shows an acceptable behaviour ...

    This paper presents a novel multiple serial code concatenation (SCC) strategy to combat the error-floor problem in iterated sparse graph-based error correcting codes such as turbo product-codes (TPC) and low-density parity-check (LDPC) codes. Although SCC has been widely used in the past to reduce the error-floor in iterative decoders, the main stumbling block for its practical application in high... View full abstract»

  • Two-channel multi-stage speech enhancement for noisy fMRI environment

    Strong acoustic noise interferes with speech communication during functional magnetic resonance imaging (fMRI) scans employing echo planar imaging (EPI) sequences. Performance of many speech enhancement (SE) methods degrades with such a low signal-to-noise ratio (SNR). In this paper, an adaptive SE method is proposed enabling noise-free online speech communication with patients and recording of cl... View full abstract»

    Future wireless systems face challenges in supporting high-rate multimedia streaming with wide coverage area and at low power. Cooperative relaying is investigated in the following context: a single base station with multiple antennas simultaneously transmits different data streams to single-antenna destinations through a set of single-antenna fixed relays, with no direct link transmission between...

  • Improved mesh models of images through the explicit representation of discontinuities

    Publication Year: 2013, Page(s):78 - 86

    A new mesh model for images that explicitly represents image discontinuities (i.e., image edges), called ERD, is introduced. Then, two mesh-generation methods, known as ERDED and ERDGPI, that select the parameters of this new model for a given image are proposed. The proposed mesh-generation methods are shown to be capable of producing image approximations of higher quality than other competing st... View full abstract»

  • A 0.9V CMOS 3-5 Ghz broadband flat gain low-noise amplifier for ultra-wide band receivers

    In this paper, a 3-5 GHz broadband flat gain low-noise amplifier (LNA) for ultra-wide band (UWB) receivers is presented. In this circuit, a cascode and cascade topology with modified input matching are designed in the frequency range of 3- 5 GHz. Choosing a common-gate technique presents greater flatness in broadband gain in the wide band frequency at the less than -3 dB input reflection coefficie... View full abstract»
