MATLAB LDPC Encoding and Decoding Implementation
Implementation Background: LDPC (Low-Density Parity Check) codes are specialized linear block codes characterized by sparse parity-check matrices where the number of "1"s is significantly fewer than "0"s. Key technical requirements include row/column weight constraints and minimal overlap between rows/columns. This MATLAB implementation involves constructing sparse parity matrices and features multiple decoding approaches including message-passing algorithms with both MATLAB-native and optimized C-based implementations.
