METHOD FOR OBTAINING ERROR CORRECTING CODE, METHOD FOR DECODING ERROR CORRECTING CODE, CODER FOR CODING BLOCK OF INFORMATION ELEMENT AND DECODER FOR DECODING FIRST BLOCK OF SOFT VALUE

Document Type and Number:

Japanese Patent JP2003218707

Kind Code:

A

Abstract:

To obtain an error correcting code of a desired parameter, without puncture processings.

According to the method of obtaining an error correcting code of a given second size N including a systematic information part of a given second size K and a redundant part, a block turbo-code is first obtained from the systematic information part and from given information elements provided at known locations, the block turbo-code includes a product of elementary systematic block codes, and at least the predetermined information elements are removed from the obtained block turbo-code to produce a shortened block turbo-code. An additional error correcting code is derived from at least a portion of the shortened block turbo-code which is stuffed with stuffing elements so as to attain a given first size. The stuffing elements are information elements of the additional error correcting codes.
