Abstract
An antenna array control method is illustrated. At least a packet is selected as at least a probing packet every probing period. One radiation pattern in a probing radiation pattern set is used to transmit the probing packet. The radiation pattern with the minimum packet error rate among all radiation patterns is selected as a best radiation pattern. When the probing period expires, a candidate radiation pattern set is obtained according to current probabilities of the radiation patterns to be the best radiation pattern. Transfer probabilities of the radiation patterns in the candidate radiation pattern set are obtained. A target radiation pattern set is obtained according to the transfer probabilities, a motion variation and trend set, and the candidate radiation pattern set. The probing period and the probing radiation pattern set are adjusted according to whether the target radiation pattern set equals to the probing radiation pattern set.
