Wireless communications system with secondary synchronization code based on values in primary synchronization code

A method of encoding a synchronization code, comprising the steps of:

• producing a primary synchronization code comprising a first code sequence;
• producing a secondary synchronization code comprising a second code sequence combined with a third code sequence, wherein the second code sequence is from a plurality of sequences, wherein each of the plurality of sequences is orthogonal with respect to all other sequences in the plurality of sequences, and wherein the third code sequence comprises a sequence of bits of the first code sequence wherein the sequence of bits of the first code sequence is consecutively repeated in the third code sequence.

A method of decoding a synchronization code, comprising the steps of:

• identifying a primary synchronization code comprising a first code sequence;
• identifying a secondary synchronization code comprising a second code sequence combined with a third code sequence, wherein the second code sequence is from a plurality of sequences, wherein each of the plurality of sequences is orthogonal with respect to all other sequences in the plurality of sequences, and wherein the third code sequence comprises a sequence of bits of the first code sequence, wherein the sequence of bits of the first code sequence is consecutively repeated in the third code sequence.
