the r&s signal generator provides you with the ability to generate signals in accordance with the standard cdma2000® 1xev-do (evolution-data optimized), rev. b. cdma2000® 1xev-do is the north american standard for the third mobile radio generation (3g). cdma2000® 1xev-do is a high-speed packet-switched transmission technique with forward peak data rates of 4.9152 mbps per carrier, designed and optimized for a datacentric broadband network.
the r&s signal generator simulates 1xev-do signal at the physical layer. in forward link (downlink) mode the signal is generated in realtime. parameter changes during active signal output take effect immediately without signal interruption. in reverse link (uplink) mode the signal is precalculated and played from the arb memory. parameter changes result in a recalculation of the signal.
the following list gives an overview of the main options provided by the r&s signal generator for generating an 1xev-do signal in accordance with 3ggp2 c.s0024-b.v3.0.
- generation of 1xev-do signals with a chip rate of 1.2288 mcps
- independent configuration of up to 4 traffic channels or 4 access terminals
- support of physical layer subtypes 0, 1, 2 and 3
- support of multi-carrier operation with up to 16 simultaneous carriers
- operating modes "traffic" and "access" on the uplink
- simulation of up to 360 additional mac users
- generation of standard compliant forward/downlink and reverse/uplink channel types
- supports configuration of public data as defined in the standard, such as long code masks for i and q channel, preamblelength, drclength etc.
- filling the data files for data channels from all possible sources of the r&s signal generator: pattern (all1, all0, user-defined up to 64 bits), pn data or data lists
- clipping for reducing the crest factor
