摘要
TDD模式移动通信系统相对于FDD系统有着独特的优势,如支持不对称业务,高频谱利用率,设备复杂度低。在介绍TDD移动通信系统特点的基础上,针对当前出现的新技术,如MIMO、智能天线、Ad-hoc、自适应调制技术TD-LAS-CDMA等,结合TDD移动通信系统的特点,分析了各技术在实际系统应用中的优缺点,最后展望在该模式下移动通信系统的发展前景。
The mobile communication system of TDD mode has unique advantages, such as providing asymmetry service, high spectrum utilization,and low complexity of devices. On the basis of introducing the system characteristic, the advantages and disadvantages of the new technologies according to the TDD system, such as MIMO , smart antenna, Ad- hoc, AMC,TD- LAS- CDMA,are analyzed in the paper. At last discusses the prospect of the TDD system.
