How ldpc works
Web27 jun. 2024 · In this method, the sender sends a redundant error-correcting code along with the data frame. The receiver performs necessary checks based upon the additional redundant bits. If it finds that the data is free from errors, it executes error-correcting code that generates the actual frame. Web30 aug. 2024 · LDPC code is simply one kind of linear block code where the dimension of H is big (e.g. 1944*972) but the percentage of 1 ’s in the Parity Matrix is very low (e.g. only …

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. http://delamare.cetuc.puc-rio.br/TVT_LLR_2015.pdf
