摘　　要：文章从频率分配、手机性价比和用户速率调整机制等方面比较了WCDMA和cdma2000这两种可能在中国使用的3G移动通信主流标准,从原理上分析了WCDMA无线接入标准在这些方面存在的技术缺陷。目前在国际市场上,WCDMA与cdma2000相比处于劣势,这也说明了文中技术分析的合理性。因此,给出的结论是应该暂缓使用WCDMA标准,应选择cdma2000及cdma20001xEV-DO标准用于我国的3G网络建设。s The comparison between WCDMA and cdma2000, the two primary standards of 3G mobile telecommunication which may be adopted in China, is given in this p aper from the aspects of the spectrum assignment, the performance-to-price ratio of handsets and the adjusting mechanism for user data rate, etc. The technical defects of WCDMA standard in these aspects are analyzed in principle. In the com petition with cdma2000, WCDMA takes the inferior position in the international m arket. This also proves the rationality of the technical analysis in this paper. The results of this paper are that WCDMA standard should be postponed to be em ployed, and cdma2000 and cdma2000 1x EV-DO should be selected to construct the 3 G networks in China.
