当前几种主流3G标准关键技术的研究
Key Technologies of Current 3G Standards
与前两代系统相比,第三代移动通信系统的主要特征是可提供丰富多彩的移动多媒体业务,其传输速率在高速移动环境中支持144kb/s,步行慢速移动环境中支持384kb/s,静止状态下支持2Mb/s。其设计目标是为了提供比第二代系统更大的系统容量、更好的通信质量,而且要能在全球范围内更好地实现无缝漫游及为用户提供包括话音、数据及多媒体等在内的多种业务,同时也要考虑与已有第二代系统的良好兼容性。
omparing with the last two generations, the 3G mobile system can provide versatile services whose data rate could reach 144kb/s in high speed environment and 384k/s in slow movements. The target of which is to accomplish much more system capacity than previous standards, including voice, data and multi-media services; and the compatibility is considered.
