Parametric localization of distributed sources
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
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
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
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 theExpand

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