  • Patent number: 9730165
    Abstract: Various aspects described herein relate to adjusting transmit power of a radio frequency (RF) transceiver. A total power adjustment for adjusting a transmit power of the RF transceiver can be determined. The transmit power can be adjusted to a first adjusted transmit power based at least in part on a first adjustment size that is less than the total power adjustment and determined based at least in part on the transmit power. Digital pre-distortion (DPD) training of the RF transceiver can be performed to adjust one or more coefficients for calibrating the RF transceiver based on the first adjusted transmit power. The first adjusted transmit power can be adjusted to a second adjusted transmit power based at least in part on a second adjustment size that is less than the total power adjustment and computed based at least in part on the first adjusted transmit power.

  • Patent number: 9722827
    Abstract: A wireless access point or other transmitter can be configured to inject a supplemental signal into a data modulated carrier signal. In some examples, a transmitter system includes an antenna, a primary modulator, and a supplemental modulator. The primary modulator receives a baseband data signal and a carrier signal and outputting to the antenna a data modulated carrier signal according to a communications protocol. The supplemental modulator injects a supplemental signal into the data modulated carrier signal by distorting the data modulated carrier signal within an error bound of the communications protocol. A corresponding receiving system includes an antenna and a supplemental signal detector for detecting the supplemental signal by detecting the distortion within the data modulated carrier signal.
