Abstract :
A prediction of the needed RF performance by using RF system simulation is indispensable when preparing commercial product for new market. This is in particular the reason for third generation (3G) wireless systems which are quite different from 2G TDMA/FDMA systems. In this case a simulation is performed for TD-SCDMA handset transmitter with the tool ADS (advanced design system). The described architecture in which the modulation is generated directly has single up conversion step. Both the baseband and RF part are simulated and analyzed, some usable results are achieved.
