Abstract

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.
