Abstract: Systems and methodologies are described that facilitate employing a scrambling code from a set of scrambling codes, which is indexed by primary synchronization codes (PSCs), to scramble or descramble a secondary synchronization code (SSC). The scrambling codes in the set can be designed to optimize peak-to-average power ratios and/or mitigate cross correlation. For example, the scrambling codes can be based on different M-sequences generated from disparate polynomials. In accordance with another example, the scrambling codes can be based on different cyclic shifts of the same M-sequence. According to another example, the scrambling codes can be based upon binary approximations of possible primary synchronization codes utilized in a wireless communication environment. Pursuant to a further example, the scrambling codes can be based on different Golay complementary sequences.

Abstract: SYSTEMS AND METHODOLOGIES ARE DESCRIBED THAT FACILITATE EMPLOYING A SCRAMBLING CODE (204) FROM A SET OF SCRAMBLING CODES (204), WHICH IS INDEXED BY PRIMARY SYNCHRONIZATION CODES (PSCS)(1004), TO SCRAMBLE OR DESCRAMBLE A SECONDARY SYNCHRONIZATION CODE (SSC)(202). THE SCRAMBLING CODES (204) IN THE SET CAN BE DESIGNED TO OPTIMIZE PEAK-TO-AVERAGE POWER RATIOS AND/OR MITIGATE CROSS CORRELATION. FOR EXAMPLE, THE SCRAMBLING CODES (204) CAN BE BASED ON DIFFERENT M-SEQUENCES GENERATED FROM DISPARATE POLYNOMIALS. IN ACCORDANCE WITH ANOTHER EXAMPLE, THE SCRAMBLING CODES (204) CAN BE BASED ON DIFFERENT CYCLIC SHIFTS OF THE SAME M SEQUENCE. ACCORDING TO ANOTHER EXAMPLE, THE SCRAMBLING CODES (204) CAN BE BASED UPON BINARY APPROXIMATIONS OF POSSIBLE PRIMARY SYNCHRONIZATION CODES (1004) UTILIZED IN A WIRELESS COMMUNICATION ENVIRONMENT. PURSUANT TO A FURTHER EXAMPLE, THE SCRAMBLING CODES (204) CAN BE BASED ON DIFFERENT GOLAY COMPLEMENTARY SEQUENCES.
