摘要：
In this article, an eigenstructure-based on-line calibration method is presented to estimate the array channel gain and phase parameters. By employing the characteristics of the DS-CDMA system, the calibration can be carried out while the system is working. So it is quite suitable for the practical application. It first estimates the initial parameters by in iteration algorithm, and then use the subspace tracking method to trace the changes of the gain and phase parameters in realtime. The proposed algorithm is described in detail, and numerical examples are provided to demonstrate the effectiveness and behavior of the calibration method.
