摘要
智能天线利用数字信号处理技术,选择合适的自适应算法,在基带动态产生空间定向波束。智能天线相当于空时滤波器,在多个指向不同用户的并行天线波束控制下,使信号在有限的方向区域发送和接收,从而提高频谱利用效率,增大系统容量。论文在分析智能天线的原理、组成和应用的基础上,最后结合TD-SCDMA系统中智能天线的特点,对其应用前景进行了展望。
By using digital tenna can dynamically produce signal processing technique and selecting appropriate adaptive algorithm, smart anspace directional beam in base band. As a space -time filter, smart antenna can improve the performance and increase the spectrum efficiency and system capacity by enhancing the receiving signal and suppressing the interfering signal. Based on the analysis of the principle, combination and application of smart antenna, the paper emphasizes the property of smart antenna in TD - SCDMA system and makes prospect oi its applications.
