Title: Flexible and programmable delta-sigma analog signal converter
Inventor: JENSEN JOSEPH F
IPC: H03M1/66
Filed: 1999-07-20
Granted: 2004-02-17
Abstract: Processing apparatus (20) that directly samples and quantizes a complex envelope of a bandlimited waveform centered at a predetermined carrier frequency. An oversampling delta-sigma modulator (21) samples and quantizes the input signal to a single bit data stream. A serial-to-parallel converter (22) converts the single bit data stream into a parallel bit stream. A digital decimation filter (23) digitally filters the parallel bit stream to produce an estimate of the baseband in-phase and quadrature components of the input signal. In-phase and quadrature video filters (27, 28) generate in-phase and quadrature samples that are output from the analog signal converter. A controller (26) and a plurality of digital-to-analog converters (25) are used to center noise shaping nulls of the delta-sigma modulator around the carrier frequency. The controller sets the spacing between nulls of the serial-to-parallel converter to maximize the signal-to-noise ratio of the analog signal. The controller controls the decimation filter to set the sample times of thereof to sample the carrier in quadrature so that the coefficients are programmed to foam a bandpass filter at the carrier frequency and programs the coefficients of the video filters to form bandpass filters at the decimated carrier frequency.

Title: Method and apparatus for aligning telescopes within a free-space optical communication system
Inventor: PRESBY HERMAN MELVIN
IPC: H04B10/118
Filed: 2001-09-24
Granted: 2006-01-24
Abstract: A free space optical communication system is disclosed whereby a transmit telescope and a receive telescope are aligned such that the point of maximum power of the received light beam is incident upon the optical fiber located at a specific point on the focal plane of the receive telescope. Such incidence is achieved by causing the transmitted beam to diverge by moving the transmit optical fiber to a point in front of the focal plane of the transmit telescope until at least a portion of the beam is incident upon the receive optical fiber. The transmit telescope and/or the receive telescope (or, alternatively, only the respective optical fibers of those telescopes) are then moved such that the point of maximum received power for that degree of divergence is incident upon the receive optical fiber. The transmit optical fiber, in response to received power measurements at the receive telescope, then incrementally moves back toward the focal plane of the transmit telescope thereby reducing the degree of divergence and achieving a greater signal per unit area at the receive telescope. As the divergence is reduced, the position of the either the transmit telescope and/or the receive telescope (or, respectively, the optical fibers) is incrementally adjusted to maximize the received power of the received signal which is incident upon the receive optical fiber for each degree of divergence. By monitoring received signal power this iterative process continues until the transmit and receive telescopes are aligned such that the transmitted beam is focused so as to maximize the received power that is incident upon the receive optical fiber.
