Abstract: In an embodiment, a method includes identifying, by a first device, a level of degradation. The method also includes transmitting, by the first device during a communication phase, a first signal with a first signal quality based on the level of degradation. The method further includes transmitting, by the first device during a second communication phase, a second signal with a second signal quality. The second signal quality may be greater than the first signal quality.

Abstract: An example apparatus includes target signal generator circuitry to generate a target signal having a first center frequency and a bandwidth. The example apparatus additionally includes companion signal generator circuitry to generate a companion signal having a second center frequency that is less than (a) the first center frequency adjusted by a first threshold and greater than (b) the first center frequency adjusted by a second threshold, the first threshold being a first multiple of the bandwidth, the second threshold being a second multiple of the bandwidth, the first multiple different than the second multiple. In some examples, the example apparatus includes adder circuitry to combine the target signal and the companion signal to form a composite signal. Additionally, the example apparatus includes transmitter circuitry to transmit the composite signal to a target device.

Abstract: A method is provided. In some examples, the method includes generating, by processing circuitry, a spread of chips representing an input bit. In addition, the method includes converting, by the processing circuitry, the spread of chips to a plurality of symbols comprising a pair of symbols. The method also includes mapping, by the processing circuitry, the pair of symbols to a single carrier signal and generating, by the processing circuitry, a radio-frequency (RF) signal based on the single carrier signal. The method further includes transmitting, by the processing circuitry via an antenna, the RF signal.

Abstract: Electronic devices and methods to provide wireless ranging are shown. A first electronic device includes a memory containing stored instructions that can perform a method for determining a distance between the first electronic device and a second electronic device. For each frequency in a selected set of frequencies, the method sets the transceiver to the respective frequency, sends a first tone having the frequency and a first phase to the second electronic device and receives a second tone having the first frequency and a second phase. For each selected frequency, the first electronic device determines the phase difference between the second tone and the controllable oscillator, receives a phase difference from the second electronic device, and calculates a phase delay for the frequency. The first electronic device calculates a phase delay difference for pairs of the frequencies; and determines the distance using these phase delay differences.

Abstract: Systems and methods of measuring distance between two wireless devices by combining phase shift and time-of-flight measurements. A first wireless devices sends a first packet to the second wireless device. After receiving the first packet, the second wireless device sending to the first wireless device a second packet. After sending the second packet, the second wireless device sends a first continuous wave signal to the first wireless device. After receiving the first continuous wave signal, the first wireless device sends to the second wireless device a second continuous wave signal. The first wireless device then calculates a time-of-flight measurement based on a time between the first wireless device sending the first packet and receiving the second packet, and calculates a second measurement based on a phase shift of the first continuous wave signal and the second continuous wave signal, and combines the two measurements.
