摘要： In the field of communications technologies, a down sampling method and a down sampling device are provided, to enable the energy of a down sampling point obtained in down sampling to be as large as possible. The down sampling method includes: extracting energy statistical values of sampling point sets in a current period; selecting a sampling position corresponding to a sampling point set with the largest energy statistical value as a down sampling position; and performing down sampling according to the down sampling position.

摘要： Method and apparatus are provided for estimating Time of Arrival (“TOA”). The method includes: performing channel estimation according to a Normal Burst (“NB”) free of interference and a local training sequence and generating a channel estimate, performing TOA estimation according to the channel estimate, and adjusting a synchronization position of the current NB according to a TOA estimation result. Interference to signals is cancelled before the TOA estimation, thus overcoming energy estimate deviation arising from interference in a strongly interfering radio environment, as occurs in the prior art, and preventing the impact on the TOA estimation. The disclosed methods and apparatus provide for more accurate energy estimates in a strongly interfering radio environment. The technical solution under the present invention does not require adjustment of the method of adjusting the search window.
