A.2 Performance of Transmitter
A.2.1 Frequency Requirement
I. Frequency coverage
450MHz band: 460 - 470MHz
800MHz band: 869 - 894MHz
II. Frequency tolerance
Within the working temperature range, the average difference between the actual
carrier frequency of CDMA transmit sector and the carrier frequency of the dedicated
transmit sector is less than
!
5
%
10
-8
(
!
0.05ppm) of the designated frequency.
A.2.2 Modulation Requirement
I. Synchronization and timing
Time tolerance for pilot frequency: The pilot time alignment error should be less than 3
l
s and shall be less than 10
l
s. For base stations supporting multiple simultaneous
CDMA Channels, the pilot time tolerance of all CDMA Channels radiated by a base
station shall be within ±1
l
s of each other.
Time tolerance of pilot channel and other code-division channels: in the same CDMA
channel, time error between the pilot channel and other forwarding code-division
channels is <
!
50ns.
The phase differences between the Pilot Channel and all other code channels sharing
the same Forward CDMA Channel should not exceed 0.05 radians and shall not
exceed 0.15 radians.
