摘　　要：传统技术无法保证在信道环境恶劣情况下的通信质量。本文提出了TD-SCDMA系统的技术特点,及其物理信道基本帧结构,深入研究了智能天线的概念、原理、自适应算法和波束赋形算法,智能天线的上下行处理过程而智能天线可以有效的对抗移动通信中的符号间干扰,多址干扰以及共信道干扰带来的性能损失,极大的提高通信质量。仿真实验证明了TD-SCDMA系统的下行波束赋形原理及其实现。Traditional technology can not guarantee the communication quality under the condition of bad channel environment. This paper presents the technical characteristics of TD-SCDMA system, and physical channel frame, in-depth study of the smart antenna concept, principle, algorithm and adaptive beamforming algorithm, smart antenna uplink and dowrdink processing process and smart antenna can effectively counter the mobile communication in the intersymbol interference, multiple access interference and co channel interference performance loss, greatly and improve the quality of communication. The simulation results show that the downlink beamfomfing principle of TD-SCDMA system and its implementation.
