Title:
METHOD FOR GENERATING A CODE AND METHOD FOR ENCODING
Document Type and Number:
WIPO Patent Application WO/2010/043569
Kind Code:
A3
Abstract:
The invention describes a code generation method, an encoding method, an encoding apparatus, and extended versions thereof. The code generation method comprises removing columns and rows from submatrices of a given matrix, and attaching a small number of additional columns thereto. The encoding method derives a codeword v in 3 parts, one of which is the given information vector u. The remaining 2 parts of the codeword are derived in a recursive, but parallelizable way. The extended versions use the generated code in a context of parallel concatenated LDPC coding.
