Abstract
Devices and methods for decoding a signal encoded using an error correcting code are provided. For example, a check node processing unit is provided for a decoder to receive at least two input messages and to generate at least one output message, each message comprising a plurality of components. The check node processing unit comprises a data structure configured to store the input messages, the components of the input messages being associated with an integer index. The check node processing unit also comprises a data processing unit configured to apply one or more iterations of a transformation operation to at least a part of the data structure depending on at least some of the components of the input messages associated with a given value of the integer index, which provides a transformed data structure. The check node processing unit further comprises a calculation unit configured to determine at least one output message from the transformed data structure.
