WCDMA and cdma2000 - The Radio Interfaces for Future Mobile Multimedia Communications - Part III

6.0 WCDMA The WCDMA scheme has been developed as a joint effort between ETSI and ARIB during the second half of 1997 [30]. The ETSI WCDMA scheme and the ARIB WCDMA scheme have been developed from the FMA2 scheme in Europe [31­37] and the Core-A scheme in Japan [38­43], respectively. The uplink of the WCDMA scheme is based mainly on the FMA2 scheme, while the downlink is based on the Core-A scheme. In this section, main technical features of the ARIB/ETSI WCDMA scheme are presented. Table 2 lists the main parameters of WCDMA [2].
