Abstract
A new ensemble of rate-compatible punctured low-density paritycheck (LDPC) codes is presented. By demonstrating the code performance analytically using the Gaussian approximation, we derive a good puncturing distribution of the proposed irregular LDPC codes. From this distribution, we show that the iterative thresholds of the proposed codes for each puncturing rate are larger than those of the standard LDPC codes. We also confirm performance of the proposed LDPC code by simulations.
