Decode Channel Type (W-CDMA(3GPP)/HSPA)

Menu Path: MeasSetup > W-CDMA(3GPP)/HSPA Demod Properties > Channel/Layer tab

Default: None (See W-CDMA(3GPP) Standard Presets Table.)

Decode Channel Type specifies the despread channel type for decoding the Despread channel.

Downlink

For Downlink, the available Channel Type choices are:

None (no decoding is performed.)
DTCH Dedicated Traffic Channel

Downlink Decode Channel Type is only available with a Spread Code Length of 128 and a Code Channel of 96. The DTCH channel is only active when Measurement Interval is set to a multiple of 30 slots.

When Downlink Decode Channel Type is set to DTCH, a DTCH CRC Cyclic Redundancy Check data field appears in the Despread Channel Syms/Errs Table, which reports a PASS/FAIL CRC decoding result.

Uplink

For Uplink, the available Channel Type choices are:

None (no decoding is performed.)
E-DPCCH E-DCH Dedicated Physical Control Channel
HS-DPCCH Dedicated Physical Control Channel (uplink) for HS-DSCH non-MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas.
HS-DPCCH Dedicated Physical Control Channel MIMO type A
HS-DPCCH MIMO type B
HS-DPCCH Dual-Cell

Uplink Decode Channel Type is only available when Measurement Interval is set to a multiple of 30 slots, with Enable HSPA Analysis selected and a Spread Code Length of 256.
