A novel method to represent the speech signals by using language and speaker independent predefined functions sets
(IEEE, 2004)
In this paper a new modeling method of speech signals is introduced. The proposed method is based on the generation of the so-called Predefined Signature S={s(R)(t)} and Envelope Function E = {e(K)(t)} Sets (PSEFS). These ...
A new speech modeling method: SYMPES
(IEEE, 2006)
In this paper, the new method of speech modeling which is called SYMPES is introduced and it is compared with the commercially available methods. It is shown that for the same compression ratio or better, SYMPES yields ...
A novel fast algorithm for speech and audio coding
(IEEE, 2007)
In this work a new mathematical modeling approach is proposed for the representation of the speech and audio signals. This approach is based on the generation of the so called Predefined Signature Sequence (PSS) and ...
Forward-viewing CMUT arrays for medical Imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2004-07)
This paper reports the design and testing of forward-viewing annular arrays fabricated using capacitive micromachined ultrasonic transducer (CMUT) technology. Recent research studies have shown that CMUTs have broad frequency ...
An immitance based tool for modelling passive one-port devices by means of darlington equivalents
(Urban & Fischer Verlag, 2001)
An immitance-based method is presented to model measured or computed data, obtained from a "passive one-port physical device" by means of its Darlington equivalent. In other words, the given data is modelled as a lossless ...
A novel method to represent speech signals
(Elsevier Science BV, 2005-01)
In this work, speech signals are modeled by means of the so-called pre-defined "signature functions". The pre-defined signature functions are generated using the statistical properties of the speech signals. It has been ...
Coherent array imaging using phased subarrays. Part II: Simulations and experimental results
(IEEE-INST Electrical Electronics Engineers Inc, 2005-01)
The basic principles and theory of phased subarray (PSA) imaging imaging provides the flexibility of reducing I he number of front-end hardware channels between that of classical synthetic aperture (CSA) imaging-which uses ...
Iterative channel estimation approach for space-time/frequency coded OFDM systems with transmitter diversity
(Assoc Elettrotecnica Ed Elettronica Italiana, 2004-06)
Focusing on transmit diversity orthogonal frequency division multiplexing (OFDM) transmission through frequency selective channels, this paper pursues novel iterative channel estimation approaches for both space-frequency ...
Annular-ring CMUT arrays for forward-looking IVUS: Transducer characterization and imaging
(IEEE, 2006-02)
In this study, a 64-element, 1.15-mm diameter annular-ring capacitive micromachined ultrasonic transducer (CMUT) array was characterized and used for forward-looking intravascular ultrasound (IVUS) imaging tests. The array ...
Cluster based sensor scheduling in a target tracking application with particle filtering
(IEEE, 2007)
In multi-sensor applications management of sensors is necessary for the classification of data they produce and for the efficient use of sensors as well. One of the important aspects in sensor management is the sensor ...
