Appendix A Performance of Receiver and
Transmitter
The technical specifications of BTS receivers and transmitters comply with or surpass
all the performance requirements defined in the IS-97-D Recommended Minimum
Performance Standards for cdma2000 Spread Spectrum Base Stations
.
A.1 Performance of Receiver
A.1.1 Frequency Coverage
z
450MHz band: 450 - 460MHz
z
800MHz band: 824 - 849MHz
z
1900MHz band: 1850 - 1910MHz
A.1.2 Access Probe Acquisition
The access probe failure ratio under the reliability of 90% is below the maximum values
listed in Table A-1:

Access probe failure ratio
Eb/N0 Per RF input point (dB)
Maximum failure rate
5.5 50%
6.5 10%
A.1.3 R-TCH Demodulation Performance
I. Performance of R-TCH in Additive White Gaussian Noise (AWGN)
The demodulation performance of the Reverse Traffic Channel in AWGN (no fading or
multipath) environment is determined by the frame error rate (FER) at specified Eb/N0
value.
FER of 4 possible data rates should be calculated respectively. With 95% confidence,
the FER for each data rate does not exceed the two given FERs in Table A-2 to Table
A-9, which adopt the linear interpolation in the form of Log
10
(FER).
