  • Patent number: 10743254
    Abstract: Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction.

  • Patent number: 10735991
    Abstract: Embodiments herein describe wireless transmission techniques for mitigating interference between wirelessly controlled machines in a shared space. To mitigate interference, the machines may be assigned different channels within the same frequency band. However, if machines using the same channel in a frequency band receive each other's wireless signals, the wireless signals can interfere. To free up additional bandwidth, in one embodiment, the command signals are transmitted using a different frequency band than a heartbeat signal used to stop the machines in case of emergencies. In another embodiment, time multiplexing or directional antennas can be used to mitigate interference. In another example, antenna diversity and multiple-input-multiple output (MIMO) can be used to further focus the radiation pattern onto the desired machine while avoiding transmitting wireless signals to neighboring machines. In one embodiment, the machines may use dual-channels to transmit and receive duplicate data.

  • Patent number: 10700912
    Abstract: A bit-level operation may be implemented prior to modulation and resource element (RE) mapping in order to generate a NoMA transmission using standard (QAM, QPSK, BPSK, etc.) modulators. In this way, the bit-level operation is exploited to achieve the benefits of NoMA (e.g., improved spectral efficiency, reduced overhead, etc.) at significantly less signal processing and hardware implementation complexity. The bit-level operation is specifically designed to produce an output bit-stream that is longer than the input bit-stream, and that includes output bit-values that are computed as a function of the input bit-values such that when the output bit-stream is subjected to modulation (e.g., m-ary QAM, QPSK, BPSK), the resulting symbols emulate a spreading operation that would otherwise have been generated from the input bit-stream, either by a NoMA-specific modulator or by a symbol-domain spreading operation.

An auxiliary signal generator may be configured to generate the auxiliary signal with relation to the RF signal as having a frequency spectrum lower than a cutoff RF frequency. Resulting lower power consumption, particularly in case of low duty cycle RF signals, reduces heating, enables longer battery use and increases reliability performance.

  • Patent number: 10693513
    Abstract: An IQ amplitude balance estimator is described herein which uses a positive frequency mixer to generate two outputs. The first output is the standard output from a positive frequency mixer and the second output corresponds to a spectrum inverted output from a negative frequency mixer. The second output is generated, however, using the same partial products as the first output and no negative frequency mixer is used. An IQ amplitude imbalance metric is generated by taking the real part of the output from correlation logic which performs a correlation of the two outputs from the mixer. This metric may then be used in a closed loop to compensate for any IQ amplitude imbalance.

  • Patent number: 10623214
    Abstract: The present disclosure relates to system(s) and method(s) for multi-level amplitude modulation and demodulation. The system accepts a frame delimiter signal, when a comparator is triggered upon receiving the frame delimiter signal from a transmitter. Further, the system receives modulated data associated with a data frame from the transmitter. In one aspect, the modulated data may be generated by modulation of the data frame using a set of three amplitude levels. Upon receiving the modulated data, the system demodulates the modulated data to retrieve the data frame along with the frame delimiter signal, which can be used for successive digital logic elements for enhanced performance.

  • Patent number: 10555287
    Abstract: Provided are a terminal device and a retransmission control method that make it possible to minimize increases in overhead in an uplink control channel (PUCCH), even if channel selection is used as the method to transmit response signals during carrier-aggregation communication using a plurality of downlink unit bands. On the basis of the generation status of uplink data and error-detection results obtained by a CRC unit, a control unit in the provided terminal uses response signal transmission rules to control the transmission of response signals or uplink control signals that indicate the generation of uplink data. If an uplink control signal and a response signal are generated simultaneously within the same transmission time unit, the control unit changes the resources allocated to the response signal and/or the phase point of the response signal in accordance with the number and position of ACKs within the error-detection result pattern.
