Notes/Equations
- This subnetwork is used to generate PICH data for test models.
The schematic for this subnetwork is shown in the following figure. The paging indicator channel (PICH) is a fixed rate (SF = 256) physical channel used to carry the paging indicator (PI). One PICH radio frame of 10 msec consists of 300 bits (b0, b1, ..., b299) and are output by WCDMA3G_TestModel_PICH_Src.
PICH radio frames are then spread by the spreading code generated by WCDMA3G_OVSF.
