Patent ID: 8675754

Claim:
A method for transmitting information to stations in a network, the method comprising: modulating first main information and a first copy of auxiliary information onto a first carrier of a signal, the first main information being modulated using a first selected region of a constellation having multiple regions, and the first copy of auxiliary information being modulated using a first selected point of a sub-constellation having multiple points within the first selected region; modulating second main information and a second copy of the auxiliary information onto a second carrier of the signal, the second main information being modulated using a second selected region of the constellation, and the second copy of the auxiliary information being modulated using a second selected point of a same sub-constellation within the second selected region, wherein the second selected point associated with the second copy of the auxiliary information occurs at a different portion of the sub-constellation than the first selected point associated with the first copy of the auxiliary information, wherein the first selected point and the second selected point alternate between multiple portions of the sub-constellation and a mapping for the first selected point and the second selected point alternate bit values; and transmitting the signal from a first station in the network to a second station in the network.
