Zusammenfassung:	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. The down sampling device includes: an extraction unit, configured to extract energy statistical values of sampling point sets in a current period; a selection unit, configured to select a sampling position corresponding to a sampling point set with the largest energy statistical value as a down sampling position; and a down sampling unit, configured to perform down sampling according to the down sampling position. The down sampling method and the down sampling device are applicable to signal processing.
