Communication apparatus and communication method using digital wavelet multi carrier transmission system

摘要

When a pilot carrier is provided in data transmission according to the DWMC transmission system, continuous identical data are given in a sub-carrier pair having predetermined adjacent two sub-carriers as a unit in plural sub-carriers on a frequency axis, whereby pilot carriers P 1 , P 2 , . . . to be sine wave signals are formed. It is possible to perform clock shift compensation or the like between a transmitter and a receiver according to complex information obtained from the pilot carriers by transmitting a transmission signal using the pilot carriers between the transmitter and the receiver.
