Notes/Equations
  1. This model is used to multiplex primary common control physical channel (PCCPCH) data.
    Each firing, 20 tokens are produced when 18 tokens are consumed.
  2. 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.
