Abstract

Abstract: A method for calibrating mismatch of channel characteristic of smart antenna is discussed.Based on physical layer standards of WCDMA wireless communication system，one new injected calibration method is presented that depends on a searcher to get complex plus of array channel and then realizes array channel characteristic mismatch calibration using estimated complex plus.Theory analysis and MATLAB simulation results show some improvement in smart antenna performance is presented.

Key words: smart antenna, channel mismatch, calibration, searcher

摘要： 研究智能天线通道不一致性的注入校正方法。基于WCDMA移动通信系统智能天线通道的物理层协议标准，提出一种新的注入校正方法。该方法首先采用搜索器估计通道的复增益，然后利用复增益的估计值实现通道不一致性的校正。理论分析和Matlab仿真表明，该注入校正方法能使智能天线的性能得以改善。
