Notes/Equations
- This model is used to multiplex primary common control physical channel (PCCPCH) data.
Each firing, 20 tokens are produced when 18 tokens are consumed. - The following figure illustrates the PCCPCH frame structure. The 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 and secondary synchronization channels (SCHs) are transmitted during this period.
This model inserts 2 bits before 18 data bits to produce a slot bit sequence of PCCPCH. In the WCDMA3G_TimeSwitch model, these 256 chips are masked by primary and secondary SCHs.
