Notes/Equations
  1. 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.
  2. 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.
