New Approaches to Beamforming, Null Steering, and Filtering

摘要

This final report consists of ten sections. The first is a report describing ourabilities in the co-site radio frequency interference (RFI) problem. The second is the paper Heisenberg Wavelets and the Uncertainty Principle, which will be expanded upon and submitted to the appropriate technical journal. The third is a revised version of the paper A Multidimensional Wiener-Wintner Theorem and Spectrum Estimation, which will appear shortly in the Transactions of the American Mathematical Society. The fourth is the expository paper Problems on Polynomials with Restricted Coefficients Arising from Questions in Antenna Theory, to appear shortly in the Proceedings of the 1989 NATO Advanced Study Institute on Fourier Analysis and its Applications. The fifth is the paper An Ideal Omnidirectional Transmitting Array, and Optimal Peak Factor Array, for Less Than Half-wavelength Spacing, to be submitted shortly to the IEEE Transactions on Antennas and propagation. The sixth is the revised paper Properties on the Unit Circle of Polynomials with Unimodular Coefficients, which just appeared in the Proceedings of the American Mathematical Society. The seventh gives an overview of awd, which is our new method of choosing shading coefficients, based on a convex programming approach. The eight is the latest revision of the paper A Specification Language Approach to Solving Convex Antenna Weight Design Problems, which will be submitted shortly to the appropriate technical journal. The ninth is version 3.0 of the awd User's Manual, incorporating several improvements which have been added recently. (SDW)
