Abstract
A data transmission method with phase shift error correction comprising: transmitting through a network a transmission signal, wherein the transmission signal comprises a reference signal component having a predetermined frequency and a data signal component; receiving the transmission signal, wherein the received transmission signal includes a phase shift error caused by the network, wherein the phase shift error is in both the received reference signal component and the received data signal component; generating a multiplier signal at a receiver having the predetermined reference frequency; using the multiplier signal to determine the phase shift error in the received transmission signal; and correcting the received data signal component using the determined phase shift error.
