Multi-carrier clock transport and synchronization

摘要

At least one implementation generates at least one time-domain sample in a multicarrier apparatus, and links a first timestamp to the at least one time-domain sample. The at least one time-domain sample may be associated with a Discrete Multi-Tone (DMT) symbol and transmitted to a receiving multicarrier apparatus. The receiving multicarrier apparatus may generate a second timestamp upon receiving the at least one time-domain sample.

1. A method, comprising:
receiving, at a multicarrier apparatus, a first timestamp linked to a time-domain sample of a Discrete Multi-Tone (DMT) symbol, the first timestamp linked to the time-domain sample of the DMT symbol corresponding to a time at which the time-domain sample was ready for transmission over a communication medium; and generating, at the multicarrier apparatus, a second timestamp upon receiving the DMT symbol having the first timestamp linked to the time-domain sample.
