• Design of Adaptive Overlays for Multi-scale Communication in Sensor Networks ﻿

(2005-06-01)
In wireless sensor networks, energy and communication bandwidth are precious resources. Traditionally, layering has been used as a design principle for network stacks; hence routing protocols assume no knowledge of the ...

In this paper, we propose a technique to decouple the problems of maximizing spatial diversity gain, temporal diversity gain, and coding gain, involved in the design of space-time codes in Rayleigh fading channels. For ...
• Design of computationally efficient multiuser detectors for CDMA systems ﻿

(1997)
Linear multiuser detectors have been developed for CDMA systems to maintain a balance between the performance and computational complexity of the detectors. However for a system with a large number of users and huge data ...

Linear multiuser detectors have been developed for CDMA systems to maintain a balance between the performance and computational complexity of the detectors. However for a system with a large number of users and huge data ...
• Design of control systems to meet l(infinity) specifications ﻿

(1993)
Three control system design problems aimed at meeting specifications given in terms of the $l\sb\infty$ norm, or peak magnitude, of disturbances and errors are solved. The specification in the first problem requires simply ...

In this thesis, a recently developed computational method for the design of linear multivariable controllers is presented. For a given linear time-invariant multi-input-multi-output system, our objective is to find a ...
• Design of Linear Phase Cosine Modulated Filter Banks for Subband Image Compression ﻿

(1994-01-15)
Wavelet methods give a flexible alternative to Fourier methods in non-stationary signal analysis. The concept of band-limitedness plays a fundamental role in Fourier analysis. Since wavelet theory replaces frequency with ...

This thesis treats the following problem: Given a multivariable linear time-invariant plant, we want to design a feedback controller in such a way that the closed loop system is internally stable and the output tracks an ...
• DESIGN OF OPTIMAL DIGITAL FILTERS (APPROXIMATION, CHEBYSHEV, LINEAR PHASE, MINIMUM PHASE, COMPLEX DOMAIN) ﻿

(1986)
Four methods for designing digital filters optimal in the Chebyshev sense are developed. The properties of these filters are investigated and compared. An analytic method for designing narrow-band FIR filters using Zolotarev ...
