This paper presents a new satellite radio interface, satellite code division multiple access (SAT‐CDMA), for the satellite component of IMT‐2000. The SAT‐CDMA was proposed by Korea and was based on wideband CDMA (WCDMA) for a high degree of commonality with the terrestrial component of IMT‐2000. Because a satellite link has a longer round trip delay and a higher Doppler shift than a terrestrial link, we developed new technologies that would make the satellite component especially efficient. We present the main features of the SAT‐CDMA radio interface by focusing on satellite‐specific schemes. We also demonstrate with extensive comparison results the performance of the main technologies in the SAT‐CDMA radio interface.
