Abstract
We have presented in this paper some experimental real-time calibration results of a CDMA transmitter/receiver for TDD systems by calculating the RF devices´ impulse responses with a least square algorithm. Radiation pattern measurements have allowed to verify the effectiveness of this calibration method.
