Claim 11:
12. A receiver comprising a receiving unit and a processing unit, wherein
the receiving unit is configured to:
receive 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; and

the processing unit is configured to:
determine 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; and
determine 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
identify 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.
