Notes/Equations
- This subnetwork is used to generate the data stream of one uplink dedicated physical data channel (DPDCH).
When GainUnit = Index, the gain of DPDCH is based on DPDCHGainIndex, otherwise it is based on parameter DPDCHGainFactor.
When MultiCHs = No, DPDCHNo must be set to 1; when MultiCHs = Yes, DPDCHNo of all DPDCHs must be serial, from 1 to the number of DPDCHs.
The schematic for this subnetwork is shown in the following figure. DPDCH random bit source is second interleaved and then spread by the spreading code generated by WCDMA3G_OVSF. The data stream is mapped onto the I-branch when DPDCHNo is odd and onto the Q-branch when DPDCHNo is even. The complex data stream is then multiplied with the scrambling code generated by WCDMA3G_UpLkScrambler.
