Notes/Equations
- This model is used to generate data source used to fill the PCCPCH frame.
The data source is generated using a 9-stage shift register. The primitive trinomial is x9 + x4 + 1. The shift register is seeded with the orthogonal spreading code index.
Each firing, 18 tokens consisting of 1 slot of PCCPCH data are generated.
