Method of and apparatus for synchronization |
摘要 |
A method and apparatus of synchronizing pulsed wireless communication between a first transceiver and a second transceiver. It includes the steps of transmitting a pulse signal from a first transceiver to a second transceiver; transmitting a reflection signal from the second transceiver to the first transceiver if the transmitted pulse signal is received at the second transceiver within an active reception period of the second transceiver; and detecting the reflection pulse to determine synchronization between the first transceiver and the second transceiver. Embodiments of the invention also relate to an apparatus for carrying out the method. In one embodiment, the reflection signal is generated by a super-regenerative oscillator. |

1. A method for synchronizing active transmission and reception timeslots of transceivers, comprising:
transmitting a transmission pulse signal from a first transceiver to a second transceiver; transmitting a reflection signal from the second transceiver to the first transceiver in response to the transmission pulse signal if the transmission pulse signal is received at the second transceiver within an active reception timeslot of the second transceiver and using timing information of a time of activation of the active reception timeslot by the second transceiver during which the transmission pulse signal has been received to establish active reception timeslots of the second transceiver for future communication; and detecting the reflection signal with the first transceiver and using timing information of a time of transmission of the transmission pulse signal to establish active transmission timeslots of the first transceiver for future communication. |
