49、rface designed to meet the requirements of the satellite component of the third generation (3G) wireless communication systems. The SW-CDMA radio interface was produced by TS 101 851. SW-CDMA is based on the adaptation to the satellite environment of the IMT-2000 CDMA Direct Spread terrestrial radio interface (UTRA FDD or WCDMA). The intention is to reuse the same core network and reuse the radio interface specifications for the Iu and Cu interface. Only the Uu interface will be adapted to the satellite environment. SW-CDMA
