cdma 2000 1xRTT Characterization
System Description
CDMA2000 is the TIA’s standard for third generation
(3G) technology 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 Avago Technologies 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 configuration consists of a reverse pilot
(R-Pilot) channel for synchronous 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 information. Channels can exist at
different rates and power levels.

CDMA2000 reverse link.
