Combined Source-Channel Coding for Bandlimited Waveform Channels
(1989)
We consider the problem of transmitting data from a continuous- ampltude, discrete-time source over a bandlimited waveform channel using a block-structured digital communication system. Our objective is to design the source ...
Reliability, Covering and Balanced Matrices
(1993)
The paper addresses a certain generalized covering integer program. The original application that motivated the study of this problem was an emergency services vehicle location problem. In this paper, we show that the same ...
Distributed Parallelism Considered Harmful
(1992)
We consider a model of a distributed parallel processing system that shows that parallel versus sequential processing is beneficial only under conditions of light load. Our results are valid under general assumptions on ...
One-Step Memory Nonlinearities for Signal Detection and Discrimination from Correlated Observations
(1992)
New detectors employing test statistics which are formed by passing pairs of consecutive observations through one-step memory nonlinearities g(x, y) and summing the resulting terms are introduced. Problems of discrimination ...
A Distributed, Object-Oriented Communication Network Simulation Testbed
(1992)
The Distributed Network Simulation Testbed is a research tool designed to aid users in the modeling and performance analysis of communication protocols. The testbed can be used to model communication networks consisting ...
Guaranteed Performance Regions for Markov Models
(1991)
A user facing a multi-user resource-sharing system considers a vector of performance measures (e.g. response times to various tasks). Acceptable performance is defined through a set in the space of performance vectors. Can ...
Ripple Analysis in Ferret Primary Auditory Cortex. II. Topographic and Columnar Distribution of Ripple Response Parameters
(1994)
We examined the columnar and topographic distribution of response parameters using spectral ripples and tonal stimuli in the primary auditory cortex (AI) of the barbiturate-anesthetized ferret. The ripple stimuli consisted ...
Conditions for the Equivalence of ARMAX and ARX Systems
(1991)
It is shown that an autoregressive moving average with exogenous input (ARMAX) system can be represented as an autoregressive with exogenous input (ARX) model if and only if the transfer function from the noise port to the ...
Performance Evaluation and Optimization of Parallel Systems with Synchronization
(1989)
This thesis considers synchronization issues such as resequencing and fork/join in parallel architectures. The discussion is carried out in the context of K parallel single server queues with general servers where jobs are ...
Comparison of Coherent WDMA and Hybrid WDMA/CDMA for the Multiplexing of Optical Signals
(1992)
In this paper, we provide an accurate analysis of the performance of coherent dense wavelength-division multiple-access (WDMA) schemes introduced for use in high-capacity optical networks. In our analysis, the effects of ...
