  • Publication number: 20240205844
    Abstract: Disclosed herein are devices, methods, and systems for adjusting transmit properties based on compliance metrics for human exposure to radiation. As one example, the system determines a first transmission power limit associated with transmissions on a first radio resource, wherein the first transmission power limit is based on a first compliance level threshold of human exposure to emitted radiation when using the first radio resource. The system determines a second transmission power limit associated with transmissions on a second radio resource, wherein the second transmission power limit is based on a second compliance level threshold of human exposure to emitted radiation when transmitting using the second radio resource. The system also controls a wireless device to select either the first radio resource or the second radio resource for a transmission from the wireless device based on the first transmission power limit and the second transmission power limit.

  • Publication number: 20220190860
    Abstract: Systems and methods of reducing SNR and increasing bandwidth of received signals are disclosed. LNAs receive signals from an antenna via a common input matching network. The amplified signals are downconverted, filtered and digitized before being coherently combined at a DSP. Depending on the LO frequencies used by mixers in the different receiver paths, the combined signals reduce the SNR when the LO frequencies are the same by reducing the non-correlated noise introduced by the LNAs or increase the bandwidth processed when the LO frequencies are different. The bandwidths are contiguous or non-contiguous.

  • Patent number: 10418942
    Abstract: Embodiments of a reference path circuit and communication device are generally described herein. The reference path circuit may include an injection locked multiplier (ILM) and a group of one or more buffer amplifiers. The ILM may receive a sinusoidal reference signal from a reference oscillator at a reference frequency. The ILM may generate a sinusoidal ILM output signal at an ILM output frequency that is based on an integer multiple of the reference frequency. The integer multiple of the reference frequency may be within a locking range of the ILM that may be based on a resonant frequency of the ILM. The group of one or more buffer amplifiers may generate an output clock signal for input to the frequency synthesizer. The output clock signal may be based on a sign function of the ILM output signal.
