Abstract
An electronic device may include wireless circuitry that conveys data with a base station according to a communication standard and that detects range to an external object using a first antenna that transmits a waveform compliant with the standard. The waveform may be a Sounding Reference Signal (SRS) waveform, a transmit data waveform, or another waveform. A second antenna may receive a reflected signal that includes the transmitted waveform. The communications circuitry may perform element-wise division on symbols of a selected sub-carrier in the reflected signal using corresponding phases and magnitudes of a set of complex OFDM symbols used to generate the transmitted waveform. Peak detection may be performed to detect the range. Using standard-compliant transmit waveforms to also perform spatial ranging may allow the communications circuitry to avoid dedicated radar circuitry while also minimizing impact to the transfer of the data.
