Web16 apr. 2009 · For any linear code, the correction capacity is determined by minimum Hamming distance. This is by definition. However, this is irrelevant for LDPCs, since LDPCs are decoded according to the distance spectrum, and the number of corrected bits does have meaning only in the statistical sense. So, the question is stupid. Webwork of Luby et al [16, 17] (studying codes based on irregular graphs was one of the big conceptual leaps made in these works). We will return to this aspect later in the survey. …
