INTERFERENCE REDUCTION TECHNIQUES STUDY.
Abstract
This document concludes the analytical phase of the Interference Reduction Techniques Study. The report begins with the analysis of the composite binomial waveform, its credibility, and applications to the candidates of minimal interference waveforms. As an introduction the key parameter of effective bandwidth is defined, justified, and applied to various waveforms. The significance of the effective bandwidth is that it serves as a figure of merit with respect to information capability of the waveform. Thus, a comparison table is formed showing the figure-of-merit and 80 dB bandwidth. As suspected, the binomial pulse had the least 80 dB bandwidth for the same figure of merit as a number of other candidates. Second to the binomial is the composite binomial for which the greater part of the report is dedicated. The composite binomial is investigated with concentration on effective bandwidth. The most significant result of the analysis is that there exists a minimum energy-bandwidth product which depends on a particular interpulse spacing for a given number of pulses to sum. This finding paved the way for a complete design criteria applied to the composite for use in the physical aspects phase of the study. (Author)
