Performance Simulation of LDPC Codes in AWGN Channel
Simulation of LDPC code performance in AWGN channel using MATLAB scripts: geth.m (H-matrix generation), getG.m (H-to-G matrix conversion), H2G.m (alternative conversion method), decode.m (encoding implementation), and BER.m (bit error rate calculation). This simulation follows traditional encoding schemes: generating H-matrix, converting to G-matrix, encoding data transmission through Gaussian channel, and evaluating BER performance.

LDPC Codes and Associated Implementation
[LDPC code] refers to papers related to LDPC codes, [WuYuFei] represents Wu YuFei's research papers, and [WuYufei_matlab] contains Wu YuFei's MATLAB implementations for Turbo codes. These programs calculate frame error rate and bit error rate under fixed signal-to-noise ratio and constraint length conditions. The main program turbo_sys_demo.m coordinates multiple subroutines: trellis.m constructs the trellis structure, logmapo.m implements the LOGMAP decoding algorithm, sova0.m executes the SOVA decoding algorithm, and encoderm.m handles encoding operations. Modified version [22] adapts Wu Yufei's original implementation to trace the evolution of prior information between two decoders with fixed frame length, SNR, and iteration count.
