Claim 0:
1. A method for synchronizing an encoded signal, the method comprising:
receiving an input signal comprising a first signal component and a second signal component, wherein a sequence of N bits of the first signal component and a sequence of M bits of the second signal component are known a priori;
determining a first logical sequence based on a plurality of cross-product operations formed between pairs of vectors obtained from a plurality of received symbols of the first signal component and the second signal component of the received input signal;
determining a second logical sequence based on logical operations performed between at least a part of the known sequence of N bits of the first signal component and a corresponding number of bits of the known sequence of M bits of the second signal component, in order to synchronize to a frame of the received input signal; and
identifying a position of the second logical sequence within the first logical sequence, the identified position reflecting a location of where the known sequence of N bits of the first signal component are identified in the received input signal.
