Notes/Equations
- This subnetwork model is used to generate up to four dedicated physical channel (DPCH) modulated data streams in downlink.
The schematic for this subnetwork is shown in the following figure. Data sources of four DPCHs (generated by four random bit sources) are QPSK data mapped, spread by their spreading codes input by pin SpreadingCodes, then multiplied by their scrambling codes generated by WCDMA3G_DnLkScrambler.
