Abstract
The disclosure relates to determining a carrier phase shift between a first transceiver and a second transceiver, each transceiver comprising a local oscillator for generating a carrier signal, an example method for which comprises: the first transceiver generating and transmitting a first continuous wave carrier signal packet; the second transceiver receiving the first continuous wave carrier signal packet; the second transceiver calculating a first phase correction based on a comparison between the received first continuous wave carrier signal packet and a local oscillator carrier signal at the second transceiver; the second transceiver generating and transmitting a second continuous wave carrier signal packet; the first transceiver receiving the second continuous wave carrier signal packet; the first transceiver calculating a second phase correction based on a comparison between the received second continuous wave carrier signal packet and a local oscillator signal at the first transceiver; and the first transceiver calculating the carrier phase shift from an average of the first and second phase corrections, wherein the local oscillator of the first transceiver is deactivated after transmitting the first continuous wave carrier signal packet and reactivated before receiving the second continuous wave carrier signal packet.
