Code Dom Channel Table
Selects the Code Domain Channel Table result display. This channel assignment table can
contain up to 512 entries, corresponding to the 512 codes that can be assigned within the class
of spreading factor 512. For detailed description of the channels refer to "Channels of the Code
Domain Channel Table and their usage" on page 4.273.
In the upper part of the Code Domain Channel Table, all channels that have to be present in the
signal to be analyzed are listed. In the lower part of the table, all data channels contained in the
signal are listed. A data channel is any channel that does not have a predefined channel number
and symbol rate.
The channels are listed in descending order according to symbol rates and, within a symbol rate,
in ascending order according to the channel numbers. Therefore, the unassigned codes are
always to be found at the end of the table.
The following parameters of these channels are determined by the code domain power
measurement:
– Chan Type
type of channel (active channels only)
If the modulation type of a channel can vary (HS–PDSCH), the value of the measured
modulation type is appended to the channel type. Data channels without a type fully recognized
are characterized as CHAN.
– SymRate [ksps]
symbol rate at which the channel is transmitted (7.5 ksps to 960 ksps).
– Chan
number of the channel spreading code (0 to [spreading factor–1]).
– Status
Unassigned codes are considered to be inactive. A data channel is considered to be active if
the required pilot symbols (see 3GPP specification, exception: PICH) are to be found at the end
of each slot. In addition, the channel should have minimum power (see Inactive Channel
Threshold softkey).
– PilotL [Bits]
number of pilot bits of the channel
– PwrAbs [dBm]/ PwrRel [dB]
