MATLAB simulation of LDPC code encoding and decoding using BPSK modulation for transmission, with comprehensive BER performance analysis including code rate and SNR variations
Detailed Documentation
I developed a MATLAB implementation for LDPC code encoding and decoding, incorporating BPSK modulation for signal transmission. The simulation evaluates system performance through bit error rate (BER) measurements. The implementation utilizes sparse matrix representation for efficient parity-check matrix handling and employs the belief propagation algorithm for iterative decoding. In the experimental analysis, I compared performance differences under various code rates and signal-to-noise ratio (SNR) conditions, demonstrating how different parameter configurations affect error correction capabilities. The BER curves were generated by systematically varying SNR values while maintaining consistent modulation and decoding parameters.
