  • Patent number: 10306565
    Abstract: Digital content can be broadcast in a sideband of an analog broadcast channel using multiple digital in-band on-channel (IBOC) transceivers connected in a mesh configuration to form an IBOC mesh network. The digital IBOC transceivers are positioned at various geographic locations, so that unlike traditional “HD” radio broadcasts, the IBOC broadcast transmission is spread out over a wide area, using multiple low power digital IBOC transceivers rather than being broadcast from the same location as the analog signal. An edge transceiver can limit IBOC transmission power of the IBOC transceivers to a desired portion of the power used to broadcast the analog signal. The edge server can make this determination based on measurements taken at the geographically distributed digital IBOC transceivers. The IBOC mesh network provides bi-directional communication between a mesh transceiver and a user device, and can be used to deliver user feedback.

  • Patent number: 9435893
    Abstract: An advanced multiple-beam GPS receiving system is achieved that is capable of simultaneously tracking multiple GPS satellites independently, detecting multiple interference signals individually, and suppressing directional gain in the antenna pattern of each beam in the interference directions. The GPS receiving system can be used for both planar and non-planar receiving arrays, including arrays that are conformally applied to the surface of a platform such as an aircraft. The GPS receiver combines spatial filtering and acquisition code correlation for enhanced rejection of interfering sources. Enhanced gain in the direction of GPS satellites and the ability to shape the beam patterns to suppress gain in the direction of interfering sources make the GPS receiving system largely insensitive to interfering and jamming signals that plague conventional GPS receivers.

    Abstract: Various embodiments are described that relate to signal distortion for delay and attenuation. A transmission antenna can transmit a baseline signal to a reception antenna and then transmit a test signal to the reception antenna. The baseline signal and test signal can be processed to determine undesirable attenuation and delay coefficients. These coefficients can be transmitted back from the reception antenna to the transmission antenna. Based on these coefficients, a determination can be made on how to modify a signal of interest such that the signal of interest arrives from the transmission antenna to the reception antenna absent the undesirable attenuation and delay coefficients. The transmission antenna can transmit the modified signal of interest such that it arrives at the reception antenna absent the undesirable delay and attenuation coefficients.

  • Patent number: 8976969
    Abstract: A method and apparatus is disclosed in which delay is applied to analog-sourced audio in a radio simulcast when the analog signal initially leads the digital signal. A radio receiver is configured to receive a simulcast radio program broadcast with an analog signal and a digital signal. The program content can be extracted from either the analog or digital signals, with the audio source eventually being blended to the digital signal. Audio is initially provided based on the analog signal. If the analog signal is initially leading the digital signal, delay is applied a data stream corresponding to the analog signal relative to a data stream corresponding to the digital signal. Delay applied to the data stream corresponding to the analog signal is increased at a rate that avoids audio artifacts of the output audio. The blend is performed when the data streams are aligned in time.
