  • Patent number: 11152700
    Abstract: In the disclosed optically-fed transmitting phased-array architecture, transmitting signals are converted between the electrical domain and the optical domain by using electro-optic (EO) modulators and photodiodes. RF signal(s) generated from a relatively low frequency source modulate an optical carrier signal. This modulated optical signal can be remotely imparted to photodiodes via optical fibers. Desired RF signals may be recovered by photo-mixing at the photodiodes whose wired RF outputs are then transmitted to radiating elements of the antennas. The antenna array may generate a physical RF beam that transmits an RF signal that is focused on one or more selectable locations. Multiple RF beams may be simultaneously generated, each RF beam being capable of being directed to focus on a unique location or set of locations.

  • Patent number: 10432280
    Abstract: Systems and methods are provided for improving uplink coverage in a wireless communication network. A first correlated array and a second correlate array each comprise a plurality of antenna elements. Each correlated array has an inter-element spacing of one wavelength of a signal for which the array is configured to receive. The first and second correlated arrays are interleaved such that one-half of a wavelength of a signal for which at least one of the correlated arrays is configured to receive separates adjacent elements of the first and second correlated arrays. Signals received by each correlated array are combined using statistical signal processing techniques to create combined signals that may be provided to the wireless communication network. Combining uplink signals from at least two interleaved uncorrelated arrays may increase the effective spacing of each array without sacrificing base station space or throughput.

  • Patent number: 10270583
    Abstract: A transmit (TX) signal path circuit in a multiple-input, multiple-output (MIMO) transceiver responsive to a digital front end (DFE) for generating receive (RX) path phase alignment signals is disclosed. A digital up-conversion block uses a first numerically-controlled oscillator (NCO) for generating digital intermediate frequency (IF) signals for ordinary TX signal generation, and a different, second NCO for generating digital IF signals for RX phase alignment signal generation. An RF up-conversion block uses a TX local oscillator (LO) for generating analog RF signals for ordinary TX signal generation, and a different feedback (FB) LO for generating analog RF signals for RX phase alignment signal generation. Thus, phase alignment of the circuitry used for ordinary TX signal generation is left undisturbed by RX phase alignment signal generation.

  • Patent number: 10222445
    Abstract: A system includes a phased array antenna that is used to emulate antennas that have larger solid angle coverage and lower gain compared to a single beam of the phased array antenna. This is achieved by switching between beams of the phased array antenna while receiving a wireless communication signal and summing representations of signal energy received using the different beams. The system can be used to narrow down the angular coordinates of a transmitting satellite by emulating antenna patterns that cover portions of a search space. The system can also be used to determine a channel discriminator (e.g., frequency, code, time slot) that defines a signal being transmitted.
