Notes/Equations
  1. This subnetwork model is used to generate primary common control physical channel (PCCPCH) modulated data that is time multiplexed with synchronization channel (SCH) data.
    The schematic for this subnetwork is shown in the following figure. Input data from pin PCCPCHIn is QPSK data mapped, then spread by spreading code Cch,256,1 generated by WCDMA3G_OVSF and multiplied by the primary scrambling code (generated by WCDMA3G_DnLkScrambler) to get PCCPCH modulated data. Primary synchronization code (PSC) is generated by WCDMA3G_PSCode; secondary synchronization code (SSC) is generated by WCDMA3G_SSCode. PSC and SSC are added on synchronization channel (SCH). PCCPCH modulated data and SCH data are periodically time multiplexed by WCDMA3G_TimeSwitch.
