Notes/Equations
- This model is used to de-multiplex primary common control physical channel (PCCPCH) data.
Each firing, 18 tokens are produced when 20 tokens are consumed. - The following figure shows the frame structure of the PCCPCH. PCCPCH is a fixed rate (30 kbps, SF= 256); downlink physical channels carry the broadcast channel (BCH). The PCCPCH is not transmitted during the first 256 chips of each slot; primary synchronization channel (SCH) and secondary SCH are transmitted during this period.
This model punctures 2 bits of the first 20 bits in one slot bit sequence. These 2 bits are inserted into WCDMA3G_PCCPCHMux.
