    Abstract: A wireless user equipment (UE) device may include a receiver and transmitter. The UE device may dynamically vary the fidelity requirements imposed on the analog signal processing performed by the receiver and/or the transmitter in response factors such as: amount of signal interference (e.g., out-of-band signal power); modulation and coding scheme; number of spatial streams; extent of transmitter leakage; and size and/or frequency location of resources allocated to the UE device. Thus, the UE device may consume less power on average than a UE device that is designed to satisfy fixed fidelity requirements associated with a worst case reception scenario and/or a worst case transmission scenario.

    Abstract: In order to maintain flexible system bandwidth and a flexible center frequency, without requiring a cyclic prefix or guard interval, a transmitter apparatus transmits a reference signal based on a single carrier waveform having a mixed symbol structure, in reference signal symbols using at least one of a cyclic prefix and a guard interval and transmits data based on the single carrier waveform without the cyclic prefix or the guard interval. The data may be based on input data processed using overlapping FFT windows, and an amount of overlap between the FFT windows may be configurable by the transmitter or the receiver. An apparatus receiving the downlink transmission comprising data based on a single carrier waveform may process the data based on overlapping FFT windows.

  • Patent number: 10664607
    Abstract: A system includes a transmit equalizer to equalize a data stream using a set of transmit parameters to generate an input signal. The system further includes a communication channel to receive the input signal. The system further includes a receive equalizer to receive an output signal from the communication channel in response to the input signal and detect the data stream from the output signal using a set of receive parameters. The system additionally includes a controller to change the set of transmit parameters in response to a condition, where the transmit parameters, the receive parameters, and the condition are selected to both enable the receive equalizer to detect the data stream from the output signal and reduce the likelihood of an external circuit detecting the data stream from the output signal.

  • Patent number: 10651886
    Abstract: A same-aperture any-frequency simultaneously transmit and receive (STAR) system includes a signal connector having a first port electrically coupled to an antenna, a second port electrically coupled to a transmit signal path, and a third port electrically coupled to receive signal path. The signal connector passes a transmit signal in the transmit signal path to the antenna and a receive signal in the receive signal path. A signal isolator is positioned in the transmit signal path to remove a residual portion of the receive signal from transmit signal path. An output of the signal isolator provides a portion of the transmit signal with the residual portion of the receive signal removed. A signal differencing device having a first input electrically coupled to the output of the signal isolator and a second input electrically coupled to the third port of the signal connector subtracts a portion of the transmit signal in the receive signal path thereby providing a more accurate receive signal.

  • Patent number: 10652131
    Abstract: A programmable logic device, such as a field programmable gate array (FPGA), is disclosed that allows for both high speed and low speed signal processing using the existing high speed transceiver. The programmable logic of the device may be programmed to include a sampling logic block that determines the low speed bit patterns from a device under test (DUT). The logic may further include a bit replication logic block that replicates bits such that the output of the device's high speed transceiver looks like a low speed signal to the DUT. The device, therefore, can communicate with the DUT at both the high and low speeds without the need for intermediate hardware.
