Semi-blind Calibration and Performance Analysis for CDMA Communications with Smart Antennas
《Chinese Journal of Electronics》2007年第3期553-557,共5页LIN Min YANG Luxi HE Zhenya 
This work is supported by the National Natural Science Foundation of China （No. 60496310 and No. 60672093; and by the Natural Science Foundation of Jiangsu Province （No. BK2005061）.
Since mutual coupling between elements always degrades the array processing performance, a semiblind calibration method is presented for such kind of model error in CDMA communications systems. The proposed method fir...
