Parametric localization of distributed sources

S. Valaee, B. Champagne, P. Kabal
Mathematics, Computer Science
IEEE Trans. Signal Process.
1 September 1995

In this paper, we consider situations where the sources are distributed in space with a parametric angular cross-correlation kernel and propose an algorithm that estimates the parameters of this model using a generalization of the MUSIC algorithm. Expand

Bit loading with BER-constraint for multicarrier systems

Alexander M. Wyglinski, F. Labeau, P. Kabal
Computer Science
IEEE Transactions on Wireless Communications
1 July 2005

We present discrete adaptive bit loading algorithms for multicarrier systems with uniform (nonadaptive) power allocation operating in a frequency selective fading environment. Expand

The computation of line spectral frequencies using Chebyshev polynomials

P. Kabal, R. Ramachandran
Mathematics, Computer Science
IEEE Trans. Acoust. Speech Signal Process.
1 December 1986

Line spectral frequencies provide an alternate parameterization of the analysis and synthesis filters used in linear predictive coding (LPC) of speech. Expand

Wideband array processing using a two-sided correlation transformation

S. Valaee, P. Kabal
Computer Science, Mathematics
IEEE Trans. Signal Process.
1995

A new method for broadband array processing is proposed. The method is based on unitary transformation of the signal subspaces. We apply a two-sided transformation on the correlation matrices of the… Expand

Partial-Response Signaling

P. Kabal, S. Pasupathy
Computer Science
IEEE Trans. Commun.
1 September 1975

This paper presents a unified study of partial-response signaling (PRS) systems and extends previous work on the comparison of PRS schemes using speed tolerance, minimum eye width, and signal-to-noise ratio (SNR) degradation. Expand

Speech/music discrimination for multimedia applications

K. El-Maleh, M. Klein, G. Petrucci, P. Kabal
Computer Science
IEEE International Conference on Acoustics…
5 June 2000

We present our results of combining the line spectral frequencies (LSFs) and zero crossing-based features for frame-level narrowband speech/music discrimination. Expand

Localization of wideband signals using least-squares and total least-squares approaches

S. Valaee, B. Champagne, P. Kabal
Mathematics, Computer Science
IEEE Trans. Signal Process.
1 May 1999

In this paper, we introduce a new focusing technique for localization of wideband signals based on a modification to the TLS (MTLS). Expand

Pitch prediction filters in speech coding

R. Ramachandran, P. Kabal
Computer Science
IEEE Trans. Acoust. Speech Signal Process.
1 April 1989

Prediction error filters which combine short-time prediction (formant prediction) with long- time prediction (pitch prediction) in a cascade connection are examined. Expand

An information theoretic approach to source enumeration in array signal processing

S. Valaee, P. Kabal
Mathematics, Computer Science
IEEE Transactions on Signal Processing
1 May 2004

In this paper, a new information theoretic algorithm is proposed for signal enumeration in array processing. Expand

Mel-frequency cepstral coefficient-based bandwidth extension of narrowband speech

Amr H. Nour-Eldin, P. Kabal
