Scale-Based Techniques in Secure and Jam-Resistant Communication Systems.

Abstract

This three-year project has focused on theoretical development and preliminary performance analysis for wavelet-based multiple access communication systems. Sets of orthonormal wavelet symbols suitable for asyn-chronous multiple access spread spectrum communications were developed. Investigation of possible countermeasures to wavelet-based communication systems led to development of a cyclostationary signal detector for which detection thresholds corresponding to desired false-alarm probabilities can be determined analytically. This detector was applied against both traditionally modulated and low probability of detection signals, including wavelet modulated signals. Some basic research on wavelet analysis performed in connection with this project led to a class of multidimensional generalizations of the wavelet transform.
