Abstract :
We use DAIS to obtain very low WER/BER estimates for linear block codes and SPA decoding on the Rayleigh frequency-flat slow-fading AWGN channel using BPSK modulation with interleaving. DAIS results for the (96, 50) LDPC code are compared with standard MC results where practical, demonstrating that DAIS obtains reliable WER/BER estimates to very low values in practical time frames.
