In this paper, we are interested in estimating the power spectral density of a stationary random signal x(n) when the signal itself is not available but some low-resolution measurements derived fromâ€¦ (More)

This paper studies the basic design challenges associated with multirate sensor arrays. A multirate sensor array is a sensor array in which each sensor node communicates a low-resolution measurementâ€¦ (More)

In recent years, the widespread availability of embedded pr ocessors and easily accessible wireless networks have resulted in a new sensing concept based on conn ecting a large number of inexpensiveâ€¦ (More)

A multi-microphone time-frequency speech masking technique is proposed. This technique utilizes both the timefrequency magnitude and phase information in order to estimate the Signal-to-Noise Ratioâ€¦ (More)

We introduce an optimality theory for finite impulse response (FIR) filterbanks using a general algebraic point of view. We consider an admissible set of FIR filterbanks and use scalability as theâ€¦ (More)

Fusion of the information provided by distributed sensors is important in the future pervasive computing systems. The objective of this paper is to quantify the relative amount of informationâ€¦ (More)

This paper considers the problem of fusing two low-rate sensors (e.g., microphones) for reconstructing one highresolution signal when time delay of arrival (TDOA) is present as well. We show thatâ€¦ (More)

This paper considers the problem of fusing the statistical information gained by a distributed network of sensors. We formulate the problem as a convex feasibility problem, that is, finding a pointâ€¦ (More)

It is well known that if the communication channel is bandlimited to W Hz one can transmit at most 2W independent symbols per second. Generalized sampling theorems, nevertheless, do not restrict suchâ€¦ (More)
