  • Patent number: 10677927
    Abstract: A method for mitigating interference in a receiver, where the received signal is transmitted in a fashion having equivalent information content in at least two distinct bands. The method compares mean power per unit bandwidth in suitably normalised sidebands and sets a rejection threshold based upon the measured levels. Bands above the threshold may be rejected from further processing. The bands may include sidebands produced by a modulation process that produces sidebands having the same informational content. The threshold may be set relative to the band having the lowest mean power per unit bandwidth or according to some other function of the bands. Also extends to a signal processor in a receiver, and a receiver. The primary focus of the application is toward the Galileo Public Regulated Service (PRS) Satellite navigation signal.

The transmitter tag comprises a power management circuit, a one-time-programmable memory (OTP), a read/write memory, a state machine for controlling/monitoring the operation of the tag. The tag goes into the high power mode when the power supply ramps up to a preset voltage level. During the high power mode, the tag consumes the higher level of electrical current as indicated by the battery current signal. Upon completion of high power consumption activity, such as OTP memory download, the tag exits the high power mode and enters the low power mode. The power supply current goes to the low level to minimize the power consumption by the tag.

  • Patent number: 10396849
    Abstract: The non-coherent ultra-wideband receiver receives an ultra-wideband (UWB) signal, consisting of pulses (or “symbols”) and uses on-off keying (OOK) modulation so that when a binary “0” is transmitted, the receiver collects noise-only samples. The receiver collects samples during the symbol (pulse) duration and sorts the samples by magnitude of voltage or energy. The receiver uses the known transmission rate and the estimated signal-to-noise ratio to retrieve a sample index from a look-up table. The receiver then compares the signal sample at the index value with a predetermined threshold voltage (or energy). If the selected sample exceeds the threshold, then it is assumed that all succeeding samples also exceed the threshold (assuming the sort is in ascending magnitude) and the pulse is present and binary “1”. Otherwise, the pulse is absent in the sampling period, and binary “0”. The process is repeated for the signal duration.

    Abstract: A frequency hopping communication system uses measured intensity values, such as RSSI (received signal strength indication) values, of RF signals previously received on a particular channel to generate a signal threshold that is tailored for the particular channel and is to be applied to subsequent frequency hopping processes. The signal threshold is used for determining whether a received RF signal is from an actual transmission or is merely background noise.

  • Patent number: 10389474
    Abstract: Embodiments for a method of dynamically tuning receivers of a wideband anti-jam modem (WAM) are provided. The method includes cyclically tuning one or more receivers through a plurality of channels except a first channel. The method also includes receiving an indication, while cyclically tuning, that one or more packets to an endpoint device behind a first WAM are to be sent to the first WAM on a second channel of the plurality of channels. In response to receiving the indication, the cyclical tuning for a first receiver of the plurality of receivers is halted and the first receiver is tuned to the second channel for a first period of time to receive the one or more messages. After the first period of time, cyclically tuning the first receiver along with any other receivers of the one or more receivers through the plurality of channels except the first channel.

  • Patent number: 10355710
    Abstract: In a multi-antenna communication system using LDPC codes, a simple method is used to effectively improve the received quality by performing a retransmittal of less data without restricting applicable LDPC codes. In a case of a non-retransmittal, a multi-antenna transmitting apparatus transmits, from two antennas, LDPC encoded data formed by LDPC encoding blocks. In a case of a retransmittal, the multi-antenna transmitting apparatus uses a transmission method, in which the diversity gain is higher than in the previous transmission, to transmit only a part of the LDPC encoded data as previously transmitted. For example, the only the part of the LDPC encoded data to be re-transmitted is transmitted from the single antenna.
