Kluwer Academic Publishers eBooks · 2005
The standardization of third generation (3G) mobile systems is accelerating at a fast pace due to the proliferation of highspeed wireless multimedia communications and wireless internet services. There are three main standards for 3G: Wideband CDMA, CDMA2000 and EDGE. The first one is single carrier CDMA with bandwidth of 5MHz, whereas the second one is multicarrier CDMA based on US narrowband CDMA (IS-95). EDGE is TDMA based. Many enabling techniques including software radio, smart antennas and digital processing devices are greatly improving the spectral efficiency of 3G systems. In this chapter, some key specifications of only WCDMA are described and discussed.
