摘要
在作为中国自有知识产权的3G技术标准、作为被ITU所确定的三大主流标准之一的TD-SCDMA,由于其具有性能好、频谱利用率高、网络规划简单、覆盖范围广、建设和维护成本低,及在能够满足宽带多媒体通信要求的同时还可适用于传输非对称业务等特点,其已成为建设中国3G网络系统的最佳方案。作为TD-SCDMA系统关键技术之一的智能天线,国际上已将之作为当代以后移动通信技术发展的主要方向之一。
As China innate intellectual property rights′3G technical standard,the achievement which of was determined by ITU TD-SCDMA three big mainstream standards,since it has good performance,the frequency spectrum use factor is high,the network planning is simple,covering a wide range of construction and maintenance costs low,and broadband multimedia communication in can meet requirements of in the meantime also can be applied to unsymmetrical transmission characteristics,its has become constructs the Chinese 3G network system′s preferred plan.As TD-SCDMA system is a key technology of smart antenna,international had as a contemporary later mobile communication technology is one of the main development direction of.
