TRANSMITTER, TRANSMISSION METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM STORING PROGRAM
First Claim
1. A transmitter comprising:
- a input unit that receives an input of a timing packet from a master device;
a delay compensation unit that obtains a packet length of the timing packet and a modulation system used for radio transmission, calculating a device-specific delay value and a first propagation delay value based on the modulation system and the packet length, and calculating a delay compensation value based on the device-specific delay value and the first propagation delay value;
a filter unit that adds the delay compensation value to a specific field of the timing packet; and
a output unit that wirelessly transmits the timing packet to a receiver.

Abstract
A transmitter is connected to a master device, and wirelessly transmits a timing packet, which is transmitted from the master device, to a receiver. The transmitter includes: an input unit for receiving an input of a timing packet from the master device; a delay compensation unit for obtaining a packet length of the timing packet and a modulation system used for radio transmission, calculating a device-specific delay value and a first propagation delay value based on the modulation system and the packet length, and calculating a delay compensation value based on the device-specific delay value and the first propagation delay value; a filter unit for adding the delay compensation value to a specific field of the timing packet; and an output unit for outputting the timing packet to the receiver.
