PICH_Ec [dB]
The Paging Indicator Channel (PICH) is a physi-
cal channel with a fixed rate and a spreading
factor of 256. On the PICH upcoming paging
messages on the S-CCPCH are displayed. The UE
must „listen“ to the PICH in order to determine
whether there is an incoming call. If a positive
paging announcement is recognized, the UE
begins to read the S-CCPCH expecting a paging
message.
AICH [dB]
The Acquisition Indicator Channel is a physical
channel with a fixed rate and a spreading factor
of 256 equating to 32 kbps. It transports the
acquisition indicators which correspond to sig-
natures on the Physical Random Access Channel
(PRACH).
OCNS [dB]
Orthogonally coded noise source. The power is
not selectable but is calculated to give the full
power level after adding all the various relative
channel powers.
OCNS
[On/Off]
Here you can activate or deactivate the orthog-
onally coded noise source.
