Abstract: A system and method of controlling communication between a satellite transceiver and a ground transceiver, where the satellite transceiver is configured to receive concurrently a plurality of messages at substantially the same carrier frequency from a plurality of ground transceivers. The satellite transceiver transmits a priority threshold indicative of a transmit power that a ground transceiver is authorized to use to transmit a message. The ground transceiver receives the priority threshold transmitted by the ground transceiver, and determines a transmit power of the transmitter to transmit a message based on a comparison of the priority threshold and a priority rating of the message.

Abstract: A satellite communication system using hierarchical modulation to transmit a plurality of modulated signals to sub-regions within a region. Each modulated signal includes high priority content and low priority content. The system includes a satellite equipped with a plurality of satellite transmitters coupled to a plurality of antenna elements, e.g. a phased array of antenna elements. The antenna elements are utilized selectively to direct a modulated signal from a satellite transmitter to a distinct sub-region. The satellite transmitters and antenna also cooperate to broadcast the high-priority content to the region such that a ground receiver traveling from a first sub-region to an adjacent second sub-region adjacent will not experience a loss of high-priority content. First low-priority content of a first modulated signal directed to the first sub-region is independent of second low-priority content of a second modulated signal directed to the second sub-region.

Abstract: An in-vehicle communication system configured to receive signals from a transmitter configured to transmit periodically a time-reference signal and receiver specific information. An information transmission time of receiver specific information is timed relative to a reference transmission time of the time-reference signal. The system includes a receiver characterized as having a receiver identification value. The receiver is configured to operate from an off-state to an on-state during an information-expected time interval to receive receiver specific information. The information-expected time interval is determined based on a reception time of the time-reference signal and the receiver identification value. This provides a way to ensure that the transmitter only transmits messages when it knows the intended receiver is on. It also ensures that the receiver is on only when messages that for that receiver are expected to be received.

Abstract: A method to decode an orthogonal frequency-division multiplex (OFDM) signal data block that includes symbol-data in a data interval, repeated-data in a cyclic-prefix (CP) guard interval, and noise. The signal is often called a CP-OFDM signal. The method includes determining a first data set based on data samples taken during a first time window of a data block. The method also includes determining a second data set based on data samples taken during a second time window of the data block, wherein the second time window is selected so that the second data set includes repeated-data not present in the first data set. The method also includes combining the first data set and the second data set in a manner effective to increase a signal-to-noise ratio of the signal. The combining process increases signal data energy more than noise data energy.

Abstract: A communication system utilizing a hierarchically modulated signal and method thereof are provided, wherein a receiver system is configured to receive a hierarchically modulated signal. The receiver system includes a receiver device configured to receive the hierarchically modulated signal, which is a function of a time domain, and including a high priority data stream that has a single carrier type modulation, and a low priority data stream having data bits that are spread over a plurality of data symbols of a high priority data modulation. The receiver system further includes a low priority processor device, which includes an OFDM decoder configured to convert the low priority data stream of the hierarchically modulated signal that is a function of the time domain to be a function of a frequency domain by utilizing a FFT, such that an output is emitted that is representative of the low priority data stream.
