A method for multi-dimensional modulation of a network protocol including control data and payload data. The method includes encoding a first sine wave with the control data; encoding a second sine wave with the payload data; and summing the first and second sine waves to generate a compound sine wave. In some embodiments, the control data is header information for a first Ethernet packet and post-payload data for a second Ethernet packet; and the payload data is payload data for the second Ethernet packet.
