| Abstract(in English) | Low-density parity-check (LDPC) codes have attracted a lot of attention in recent years, because LDPC codes have a significant outcome of channel capacity at low complexity. In this paper, we propose time-invariant and time-varying LDPC convolutional codes (LDPC-CCs) based on the parity check polynomial of convolutional codes, and evaluate BER (Bit Error Rate) performances of the proposed LDPC-CCs. For comparison, BER performance in (753,561)_8 convolutional codes which have been put to practical use in wireless communication systems, employing Viterbi decoding is computed by the simulation. According to the results of the comparisons, it is important to introduce time-variance in the proposed LDPC-CCs based on the parity check polynomial of convolutional codes in order to obtain better BER performance than that employing Viterbi decoding in the (753,561)_8 convolutional codes. |
