| 摘要 |
This invention relates to a method, device, computer program and computer program product for determining a mapping for a sequence of information-carrying values, including determining K representations of a sequence of information-carrying values in K successive stages, respectively, wherein in a first stage, a first representation of said K representations is determined to be equal to said sequence of information-carrying values, wherein in subsequent stages, each representation is determined by performing a mapping operation on the representation determined in the preceding stage, and wherein said mapping operation is the same for each stage; calculating, in each stage, a parameter from a transformation of the representation determined in said stage; and determining for which stage of said K stages an extreme value of said parameter is calculated. The invention further relates to a method, device, computer program and computer program product for inverse-mapping a mapped sequence of information-carrying values, and a system for the transfer of information-carrying values.
