LDPC2
。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。(. Parallel Concatenated LDPC code is different by a plurality of bit-rate sub-code, the LDPC code rate is variable obtained after parallel concatenation. In this paper, the incremental redundancy HARQ scheme based on parallel concatenated LDPC codes, the throughput performance of this program is given closed-form solution. In AwGN channel and Rayleigh fading channels through simulation, the performance of the performance of the new program and random LDPC codes are compared. The results show that the parallel concatenated LDPC codes incremental redundancy HARQ scheme performance close to the random LDPc code, but compiled more simple decoding a wider range of parameter selection.)
