cdma 2000 1xRTT Characterization
System Description
CDMA2000 is the TIA’s standard
for third generation (3G) technol-
ogy and is an evolution of the
IS-95 CDMA format. CDMA2000
includes 1X RTT in the single-
carrier mode and 3X RTT in the
multi-carrier mode. This paper
describes the CDMA2000 1X RTT
approach and its performance
with Agilent 4x4 CDMA PAs,
ACPM-7813. CDMA2000 1X RTT,
being an extension of the IS-95
standard, has a chip rate of
1.2288Mchip/s. However, in
1xRTT, the reverse link transmits
more than one code channel to
accommodate the high data
rates. The minimum configura-
tion consists of a reverse pilot
(R-Pilot) channel for synchro-
nous detection by the Base
Transceiver System (BTS) and a
reverse fundamental channel
(R-FCH) for voice. Additional
channels such as the reverse
supplemental channels (R-SCHs)
and the reverse dedicated
channel (R-DCCH) are used to
send data or signaling informa-
tion. Channels can exist at
different rates and power levels.
Table 1 shows the transmitter
specification in CDMA2000
reverse link.
Typical channel configurations below are based on the transmitter test condition in the reverse link.
1) “Basic” Voice only configuration
– R-PICH @ -5.3 dB
– R-FCH @ -1.5 dB 9.6 kbps
2) Voice and Data configuration
– R-PICH @ -5.3 dB
– R-FCH @ -4.54 dB 9.6 kbps
– R-SCH1 @ -4.54 dB 9.6 kbps
