The Analytical Description of Regular LDPC Codes Correcting Ability
Transport and Telecommunication, 2014 The analytical description of regular LDPC (Low-Density Parity Check) codes correcting ability has been investigated. The statistical dependencies for the maximum number of corrected bits per the code word as a function of LDPC code word length and code ...
