Notes/Equations
- This subnetwork is used to perform dedicated physical channel (DPCH) de-multiplexing in downlink.
The schematic for this subnetwork is shown in the following figure. The input complex data stream is converted into I and Q streams by CxToRect then synchronously combined into one data stream by Commutator2. DPCH data is de-multiplexed by WCDMA3G_DnLkDeMux to get dedicated physical data channel (DPDCH) data, transmit power control (TPC) bits and transport format combination indicator (TFCI) bits. DPDCH data is second de-interleaved by WCDMA3G_SecondDeintlvr.
