CLOCK SYNCHRONIZATION METHOD AND COMMUNICATION APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18349229 titled 'CLOCK SYNCHRONIZATION METHOD AND COMMUNICATION APPARATUS

Simplified Explanation

The patent application describes a method and apparatus for clock synchronization and communication.

• Multiplexing a local analog clock signal and a first data signal to obtain a first multiplexed signal.
• Sending the first multiplexed signal to a first apparatus.
• Receiving a second multiplexed signal from the first apparatus.
• Demultiplexing the second multiplexed signal to obtain a second data signal and a first analog clock signal.
• The first analog clock signal corresponds to the local analog clock signal after it has gone through a transmission delay.
• Obtaining a first signal based on the first analog clock signal.
• The first signal can be a delay compensation amount or a second analog clock signal.
• The second analog clock signal is obtained by applying delay compensation to the local analog clock signal.
• Processing data based on the first signal to obtain the first data signal, to which delay compensation has been applied.

Original Abstract Submitted

A clock synchronization method and a communication apparatus are provided. The method includes: multiplexing a local analog clock signal and a first data signal to obtain a first multiplexed signal; sending the first multiplexed signal to a first apparatus; receiving a second multiplexed signal from the first apparatus; demultiplexing the second multiplexed signal to obtain a second data signal and a first analog clock signal, where the first analog clock signal corresponds to the local analog clock signal after it has gone through a transmission delay; obtaining a first signal based on the first analog clock signal, where the first signal is a delay compensation amount or a second analog clock signal, and the second analog clock signal is obtained by applying delay compensation to the local analog clock signal; and processing data based on the first signal to obtain the first data signal, to which delay compensation has been applied.
