Notes/Equations
- This subnetwork is the uplink receiver to decode HS-DPCCH. This receiver outputs decoded HARQ-Ack and CQI messages and the envelope ratio between HS-DPCCH and DPCCH.
The schematic for this subnetwork is shown in the following figure.
3GPPFDD_HS_Uplink_Rx Schematic
- This receiver decodes the 3GPPFDD_HS_Uplink source. 3GPPFDD_HS_Rake de-spreads and de-modulates the HS-DPCCH channel. The Rake receiver output is de-multiplexed as coded HARQ-Ack and CQI bit frames. The HARQ-Ack and CQI messages are recovered by channel decoder.
- The CQI output, controlled by CQI_Type, can be a decimal or a binary number.
