Abstract: Methods and systems are provided for accessing GPS signals in faded environments. Means are provided for predicting the nonlinear phase induced by the receiver's own clock, when there is at least one GPS satellite link strong enough to calculate a phase profile. In an embodiment, GPS signals are accessed in faded environments by increasing the sensitivity of a GPS receiver by increasing the processing gain of received GPS signals through increased integration time. Matching a near-baseband signal requires removing a nonlinear part of the phase which may arise from several sources, including: the phase drift of the GPS satellite's atomic clock, the phase drift due to the motion of the GPS receiver, the phase drift due to the motion of the GPS satellite, and the phase drift due to the GPS receiver's clock.

Abstract: General algebraic space-time code constructions are presented for Gray-mapped 2K-PSK, 2K-PAM, and 4K-QAM constellations. The space-time codes achieve the rate-diversity tradeoff—i.e., they allow the transmission of information at the maximum rate possible for the given signaling constellation and the achieved transmit diversity level. New codes created by applying a nonsingular linear or affine transformation to the constellation labels retain the optimality of the original codes with respect to the rate-diversity tradeoff. Extensions to pK-PSK, pK-PAM, p2K-QAM, and related constellations, for p prime, are also given.

Abstract: Techniques for filtering light include, along a central optical axis, an entrance window; a first polarizer, a narrowband polarization-changing material, a second polarizer, and an exit window. The optical paths through the filter are substantively unscattered and pass through unstressed components between the polarizers. The polarization-changing material changes polarization for a narrow wavelength band on the order of about 0.01×10?9 meters and does not condense on optical windows and polarizers during the operational lifetime. An aspect ratio, defined by a distance from the entrance window to the exit window divided by an optical aperture for the entrance window, is less than 4/1. This filter thus transmits light substantively unattenuated in the narrow wavelength band up to a maximum acceptance angle greater than 5 degrees. Combined with optics and imaging detectors, it is suitable for wide area surveillance, including daylight surveillance for combustion like forest fire and missile plume.
