Abstract

The applications of adaptive arrays based on the digital beam formingtechnique are receiving wide attention. However, the adaptive control algorithm of the array antennas under TDMA systems is not well considered even though it requires particular consideration due to its intermittent bursts. Inthis paper, first, we propose a novelDOA(Direction of Arrival)estimation method which is suitable for TDMA bursts. Second, the HA(Howells-Applebaum)adaptive array based on the proposed DOAestimation method will be constructedfor the terminals in the mobile communication systems using non-geo-stationary satellites. Then the performance of the DOA estimation method and the HAadaptive array will be examined through computer simulations and experiments.
