| Research Abstract |
The contributions of this research are summarized in the following three issues : (1) Clarification of the relation between the condition on which the sum-product decoding converges and the structure of LDPC codes from the view point of the sufficient condition on which the sum-product algorithm converges, (2) Introduction of the mathematical framework for the reversible codes and their systematic construction, (3) Developing linear time encoding algorithm for LDPC codes.
