Abstract : This report discusses the following subjects: (1) A new technique to achieve a fast PN Acquisition scheme; (2) A comparison of schemes for coarse acquisition of frequency-hopped spread-spectrum signals; (3) Investigation of the tracking of frequency hopped spread spectrum signals in adverse environments; (4) Coherent optical production of the Hough transform; (5) Estimation of the closely spaced frequencies buried in white noise using linear programming; (6) Restoration of discrete Fourier spectra using linear programming; (7) Two-dimensional optical filtering of 1-D signals; (8) Random TDMA Access Protocol with application to multi beam satellites; and (9) A reservations scheme of multiple access for local networks.
