Abstract

For several years, code-division multiple access (CDMA) systems have gained widespread interest in mobile wireless communications. Wideband code division multiple access (WCDMA) [ETSI98] uses a wider channel compared to a narrowband CDMA channel [TIA93], which improves frequency diversity effects and therefore reduces fading problems. Due to its resistance to multipath fading, and other advantages such as increased capacity, the WCDMA was selected by the European Telecommunications Standards Institute (ETSI) for wideband wireless access to support third-generation services. This technology is optimized to make possible very high-speed multimedia services such as full-motion video, Internet access and videoconferencing.
