Transmitter intermodulation
performance
If one BTS transmits at the rated power but another BTS’
output power is 30 dB less than the former’s rated power.
When the powers of two BTSs are combined on the antenna
port, the generated intermodulation spurious emission
meets the conducted spurious emission requirement. The
IF difference of the transmit signals of two BTSs is 1.25M.
Pilot time tolerance The PN time tolerance falls within 3 us and the inter-carrier
tolerance falls within 1 us.
Time difference: < ±50 ns Time Tolerance/phase tolerance of pilot
channel to other channels
Phase difference: < 0.05 rad
Waveform quality Rho is greater than 0.970 dBm with configuration of a
single pilot.
Pilot code domain power With the standard 9CH configuration, the pilot code domain
power is in the range of -7.0±0.5 dB.
Inactive channel code domain power With the standard 9CH configuration, the inactive channel
code domain power is less than -27 dB.
