Abstract
We study the effects of quantization at the output of a binary-input additive white Gaussian noise (BIAWGN) channel on the performance of low-density parity-check (LDPC) codes. The LDPC decoder works with unlimited precision. The quantizer design is based on either optimizing the equivalent channel capacity, cutoff-rate, mean-squared error (MSE) or the LDPC code convergence. All the approaches are compared in search of the most appropriate design criterion.
