Abstract: 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.

Abstract: A super-regenerative transceiver that has an antenna interface for an antenna is self-tuned with a self-tuning unit configured. The self-tuning unit makes the transceiver to repeatedly perform a self-tuning cycle until the amplitude meets a predetermined detection condition or a predetermined criterion is met. The self-tuning cycle involves the following: transmitting to the antenna a probe signal with one or more pulses; receiving from the antenna a ringing detection signal; determining if the ringing detection signal reflects tails of the probe signal with amplitude meeting a predetermined detection condition; and adjusting of the tuning of the super-regenerative transceiver if the amplitude does not meet the predetermined detection condition.
