摘要
The Rake receiver uses a delayed version of the received sequence and a delayed version of scrambling code. The flexible hardware structure of the time-aligning and descrambling unit (DSU) comprises at least two delay chains (DCH1, DCH2A) and one multiplier (MTM). By controlling two multiplexers (MUX1, MUX2), the delayed versions of the received sequence can be multiplied with an arbitrary scrambling code having an arbitrary phase. During one chip period, for each path to be processed, one multiplication is performed.
