SCRAMBLING CODE GENERATION METHOD, APPARATUS AND SCRAMBLING CODE PROCESSING APPARATUS

摘要

Provided are a scrambling code generation method, apparatus and a scrambling code processing apparatus, the method comprising the steps of converting the inputted phase shift into a binary number, according to the position of the effective bit with the highest weight in the binary number to generate an access address of a rotation factor, according to the access address to select a corresponding rotation factor from a rotation factor table; mapping a K bits original scrambling code sequence to a 2K bits scrambling code sequence, and calculating the mapped scrambling code sequence with the rotation factor to obtain the rotated scrambling code sequence; updating the effective bit with the highest weight to zero; if the updated phase shift is zero, outputting the rotated scrambling code sequence, and if the updated phase shift is not zero, regarding the updated phase shift as the present inputted phase shift and the rotated scrambling code sequence as the original scrambling code sequence, and repeating the above processes. The solution improves the performance and the flexibility, furthermore has a lower cost.
