Notes/Equations
- This subnetwork model is used to perform dedicated physical channel (DPCH) multiplexing in downlink, including the second interleaving, QPSK data mapping, space time transmit diversity (STTD) encoding and multiplexing.
The schematic for this subnetwork is shown in the following figure. Data of dedicated physical data channel (DPDCH) input by pin In is second-interleaved by WCDMA3G_SecondIntlvr. Then it and transmit power control (TPC) bits, transport format combination indicator (TFCI) bits are multiplexed in WCDMA3G_DnLkMux to make up the frame structure of DPCH. DPCH data is QPSK mapped by WCMA3G_QPSKDataMap. After data is STTD coded, corresponding pilot symbols are inserted by WCDMA3G_STTDMux.
