Patent ID: 8014479

Claim:
A method for communicating sub-synchronization information in a communication system, comprising the steps of: generating a data stream comprising pre-amble information having a first period; introducing phase-rotated sub-synchronization information into the data stream at a second period less than that of the first period of the pre-amble information, wherein a modified signal has a wobbling effect that is biased in a known direction; transmitting the modified signal comprising the data stream containing the sub-synchronization information to one or more receivers; receiving via one or more updated, coherent receivers the modified transmitted signal containing the sub-synchronization information, wherein the introduction of the sub-synchronization information comprises the sub-synchronization information modifying data in the data stream; switching among a plurality of antennas, and passing the received signal from one antenna; extracting the sub-synchronization information from the transmitted signal via the one or more updated, coherent receivers; decoding the transmitted signal using the extracted sub-synchronization information via the one or more updated, coherent receivers, wherein the extracted sub-synchronization information is used to correct for at least one of phase and polarity ambiguity in the received signal, the phase ambiguities being resolved based upon the wobbling effect being biased in a known direction, wherein a quadrature (“Q”) bit ambiguity and an in-phase (“I”) bit ambiguity are resolved at different times, which allows for quickly switching among the plurality of antennas; and receiving via one or more non-updated receivers, the modified transmitted signal, wherein the sub-synchronization information appears as noise, wherein the Q ambiguity is solved by an algorithm comprising if Q data=1, then send I=I and Q=1, else send I=sign (I)*sqrt (2) and Q=0, and the I ambiguity is solved by an algorithm comprising if I data=1, then send Q=Q and I=1, else send Q=sign (Q)*sqrt (2) and I=0.
