APPARATUS AND METHOD FOR GENERATING SCRAMBLING CODES

摘要

A wireless WCDMA (wideband code division multiple access) receiver comprises a plurality of fingers, a mask engine, a plurality of delay mask scrambling code generators and a maximal ratio combiner. Each finger process a path of a received multi-path signal having an associated delay. For each of the delays, the mask engine provides a corresponding delay mask to a delay mask scrambling code generator, which then provides a scrambling code with the appropriate offset, or delay, to the requisite finger. Output signals from the fingers are provided to the maximal ratio combiner.
