<p>A method and apparatus for multi-user asynchronous information detection are disclosed and belong to the wireless communications technical field. The method includes the following steps channel estimation is performed respectively based on at least two preset asynchronous information of other users against a benchmark user to obtain at least two groups of channel factors; the information of the receiving antennas is calculated based on the at least two groups of channel factors and the asynchronous information of the other users against the benchmark user is detected based on the information of the receiving antennas. Alternatively, the method includes the following steps : channel estimation of at least two users is performed to obtain at least two pieces of frame synchronous information, the difference of the frame synchronous information; between other users and a predetermined user is calculated by benchmarking against the predetermined user to obtain the asynchronous information of other users against the benchmark user. The apparatus includes a channel estimation module and an asynchronous information detection module. Alternatively, the apparatus includes a first computing module and a second computing module. The technical schemes provided by present invention can detect the asynchronous information of the multiple users and improve the receiving performance substantially.</p> |
