| Abstract(in English) | We propose the Normalized belief propagation (BP) based algorithms for Low-Density Pairty-Check (LDPC) Codes on fast and slow fading channels. The two proposed algorithms are universal as they do not need a priori information about the channel state and have a lower decoding complexity than the BP algorithm. We also evaluate the effects of quantization on the error rate performance of LDPC codes with the Normalized BP-based algorithm on the fast fading channel. Fron the simulation results, we show that the Normalized BP-based algorithm achieves very good trade-off between the decoding complexity and the error rate performance on a fast fading channel. We also show that the error rate performance of the Normalized BP-based algorithm is almost identical to those of the BP algorithm and the UMP BP-based algorithm on the slow fading channel. Moreover, we show that in the Normalized BP-based algorithm on the fast fading channel, the error rate performance for 5-bit quantization is identical to that for no quantization. |
