- Abstract
- The problem of calibration has arisen because the phase characteristics of signal paths associated with each antenna in a smart antenna system (SAS) are different (in both receiving (RX) and transmitting (TX) modes). In this paper, we propose a simple and accurate calibration technique for eliminating the phase characteristic difference of the signal path associated with each antenna element in both RX and TX modes. Also, through the experimental data obtained from SAS, which has been implemented with the CDMA2000 IX standard, we confirm that the proposed technique has eliminated the characteristic difference.
