Notes/Equations
- This subnetwork is used to generate the source data transmitted by base station for test on peak code domain error.
The schematic for this subnetwork is shown in the following figure. It includes several types of physical channels: PCCPCH+SCH, Primary CPICH, PICH, and 16 or 32 DPCHs. Power fractions and delays of these channels are listed in the following table. The whole gain factor of these channels is set by ModelGainFactor.
