Distributed coordination in network information theory
(Massachusetts Institute of Technology, 2001)
Constructing a large-scale wireless data network is spectacularly expensive. It is therefore important to understand how to efficiently utilize the physical infrastructure and available battery power, which are expensive ...
Information theoretic analysis of watermarking systems
(Massachusetts Institute of Technology, 2001)
Watermarking models a copyright protection mechanism where an original data sequence is modified before distribution to the public in order to embed some extra information. The embedding should be transparent (i.e., the ...
Modeling the effects of systematic process variation of circuit performance
(Massachusetts Institute of Technology, 2001)
List decoding of error-correcting codes
(Massachusetts Institute of Technology, 2001)
Error-correcting codes are combinatorial objects designed to cope with the problem of reliable transmission of information on a noisy channel. A fundamental algorithmic challenge in coding theory and practice is to efficiently ...
Design, development and characterization of an integrated multispectral polarimetric sensor system
(Massachusetts Institute of Technology, 2001)
In this thesis, a new type of integrated imaging sensor is introduced to detect multispectral and polarimetric signatures in an infrared scene. The sensor is a stack consisting of an infrared detector array, and an array ...
Interactive spectral analysis learning module
(Massachusetts Institute of Technology, 2001)
Due to increased demand for interactive learning opportunities for engineering students, an interactive spectral analysis learning module was developed for the course Biomedical Signal and Image Processing (HST582J/6.555 ...
Capacity of Gaussian noise channels with side information and feedback
(Massachusetts Institute of Technology, 2001)
In wireless communication systems, the communication channel is often modeled as a fading multiaccess channel with time-varying multipath. Because of the mobility of the users and the varying number of users, the transmission ...
Generalized frequency modulation
(Massachusetts Institute of Technology, 2001)
In frequency modulation (FM) systems, a continuous-time information signal is modulated onto a sinusoidal carrier wave by using the information signal to modulate the frequency of the carrier wave. In this thesis, a more ...
Exploring scatterer anisotrophy in synthetic aperture radar via sub-aperture analysis
(Massachusetts Institute of Technology, 2001)
Scattering from man-made objects in SAR imagery exhibits aspect and frequency dependencies which are not always well modeled by standard SAR imaging techniques based on the ideal point scattering model. This is particularly ...
Temporal characterization of patient state with applications to prediction of tachycardia in anesthesia via induction of inhaled desflurane
(Massachusetts Institute of Technology, 2001)
It has always been assumed that using clinically measurable parameters is the most efficient way to characterize patient state. By adding additional sensors, monitors, and derived statistics (e.g. mean arterial blood ...
