| 摘 要： | 并行级联LDPC码是由多个码率不同的子码,经并行级联后得到的码率可变的LDPC码.本文提出了基于并行级联:LDPC码的递增冗余HARQ方案,给出了这种方案的吞吐量性能封闭解.在AWGN信道和Rayleigh衰落信道下,通过仿真将新方案的性能和随机LDPC码的性能进行了比较.结果显示,并行级联LDPC码的递增冗余HARQ方案性能接近随机LDPC码,但编、译码更简单,参数选择范围更广. |

| Abstract: | Parallel Concatenated LDPC codes which combine of different rate component codes are Rate-compatible codes.An Incremental redundancy hybrid ARQ scheme based on parallel concatenated LDPC codes is introduced.We study the throughput of the new HARQ scheme and obtain the closed_form solutions.Furthermore,the throughput of the new HARQ scheme is simulated.It shows that for arbitrary block fading channel,comprising AWGN channel,the performance of IR_HARQ schemes based on PC_LDPC is same as those based on random ... |
