Title:
COMMUNICATION DEVICE, COMMUNICATION METHOD, COMMUNICATION PROGRAM, AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/181257
Kind Code:
A1
Abstract:
Provided is a communication device which: adds data, which is obtained by sampling repeatedly incoming packets with a clock of an N1 times frequency of a communication speed, to a result of an addition up to a directly previous packet whenever the packet is incoming; holds a processing result of a first digital filter of N2 taps (where N2 is an integer of 2 to N1) that processes the data in synchronicity with the sampling clock; reproduces a clock waveform included in bit data from a processing result of a second digital filter of N3 taps (where N3 is an integer of 2 to N1) that processes, in synchronicity with the sampling clock, an addition result, which is obtained by adding data obtained by sampling each bit composing the incoming packets with the clock of an N1 times frequency of a communication speed to the cumulative result up to the directly previous bit whenever a next bit is incoming; and plays back the sampling clock synchronized to the incoming packet from the reproduced clock waveform.
