Abstract
A decoding device for a linear code on a ring R, the decoding device including: a plurality of storage media; and a processing section; wherein the processing section uses a part of reliability of all symbols at a previous time to update reliability of each symbol in a process of iterative decoding for increasing the reliability of each symbol, and further retains a part used to update retained reliability information and a part unused to update the retained reliability information on two separate storage media.
Claims26
A decoding device for a linear code on a ring R, said decoding device comprising:
- a plurality of storage media;
- and
- a processing section;
- wherein said processing section uses a part of reliability of all symbols at a previous time to update reliability of each symbol in a process of iterative decoding for increasing the reliability of each symbol, and further retains a part used to update retained reliability information and a part unused to update the retained reliability information on two separate storage media.
A decoding method for a linear code on a ring R,
- wherein a part of reliability of all symbols at a previous time is used to update reliability of each symbol in a process of iterative decoding for increasing the reliability of each symbol, and further a part used to update retained reliability information and a part unused to update the retained reliability information are retained on two separate storage media.
