Antenna array control method and access point using the same

摘要

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.

1. An antenna array control method, comprising:
selecting at least a packet as at least a probing packet every probing period; using one radiation pattern in a probing radiation pattern set to transmit the probing packet; selecting the radiation pattern with the minimum packet error rate among all radiation patterns as a best radiation pattern; when the probing period expires, obtaining a candidate radiation pattern set according to current probabilities of the radiation patterns to be the best radiation pattern; obtaining transfer probabilities of the radiation patterns in the candidate radiation pattern set; obtaining a target radiation pattern set according to the transfer probabilities, a motion variation and trend set, and the candidate radiation pattern set; and adjusting the probing period and the probing radiation pattern set according to whether the target radiation pattern set equals to the probing radiation pattern set; wherein when the target radiation pattern set is equal to the probing radiation pattern set, the probing period is increased, and at least one radiation pattern in the probing radiation pattern set is removed therefrom; wherein when the target radiation pattern set is not equal to the probing radiation pattern set, the probing period is decreased, and at least one radiation pattern is added in the probing radiation pattern set.
