Approximation of Toeplitz matrices with circulant matrices is a well-known approach to reduce the computational complexity of linear equalizers. This paper presents a novel technique to compute linear equalizer coefficients in the frequency domain. It is s ...

This thesis describes innovative techniques for reducing speckle noise and improving the intensity profile of the speckle correlation fringes. The methods are based on reducing the range of the modulation intensity values of the speckle interference patter ...
This paper presents a new two-sections architecture of a low power switched capacitor (SC) finite impulse response (FIR) filter suitable for base-band signal processing in WCDMA and in GSM standards. The low power operation is possible due to several optim ...
The possibility to use information from cortical neurons to drive neuroprosthetic devices is an area that has recently garnered a lot of attention within neuroscience. Most of this research has been directed towards restoring upper limb motility. In this s ...
A conception as well as a CMOS implementation of the analog, ultra low power and fully parallel image processor have been presented in this paper. Proposed circuit bases on the 2-D FIR filters realized using the Gilbert vector multiplier. Proposed filter e ...
We propose a new auditory inspired feature extraction technique for automatic speech recognition (ASR). Features are extracted by filtering the temporal trajectory of spectral energies in each critical band of speech by a bank of finite impulse response (F ...
In this paper the problem of intensity inhomogeneity at high magnetic field on magnetic resonance images is addressed. Specifically, rat brain images at 9.4T acquired with a surface coil are bias corrected. We propose a low- pass frequency model that takes ...
In this work we derive a theory of polariton condensation based on the theory of interacting Bose particles. In particular, we describe self-consistently the linear exciton-photon coupling and the exciton-nonlinearities, by generalizing the Hartree-Fock-Po ...

This paper proposes a novel multilevel Power Electronics Building Block (PEBB) for the 5 level ANPC multilevel voltage source inverter [7]. The PEBB is composed of 6 switches in a crossed configuration [8] and one capacitor. It is common to the 3 phases of ...
This paper describes employment of non-uniform QMF decomposition to increase the efficiency of a generic wide-band audio coding system based on Frequency Domain Linear Prediction (FDLP). The base line FDLP codec, operating at high bit-rates (~136 kbps), ex ...
