Code
F-PICH Forward
Pilot Chan-
nel
The F-PICH is transmitted con-
tinuously on the forward signal.
The F-PICH contains only
0
bits
and the PN sequence is short.
Thus the mobile station can syn-
chronize to these sequences to
acquire the timing of the forward
channel, phase references for
coherent detection and power
references for power schemes.

F-Sync
Forward
Sync Chan-
nel
The F-Sync transmits the syn-
chronization message for the
mobile station. The message
contains the PN offset, the sys-
tem time, the long code status,
information about the paging
channel, the system ID and the
network ID.
The data rate is always 1200
bps.
