摘要

提出了一种准循环扩展方法，用于提高长度自适应多边缘型(MET)准循环LDPC (QC-LDPC)码的性能，该码的块错误率(BLER)低于10−5。提出的方法允许通过5G eMBB基图2的模块化提升来构建可变码长的MET QC-LDPC码。给出了基于QPSK调制的AWGN信道50次和积译码的仿真结果。与5G eMBB代码相比，它在信息长度k < 600和k > 600的0.1 - 0.3 dB增益范围内显示出几乎相同的性能。

Interleaved Cyclic Group Decomposition Length Adaptive MET QC-LDPC Codes

We introduce quasi-cyclic extension method for performance improving of the length adaptive Multi-Edge Type (MET) Quasi-cyclic LDPC (QC-LDPC) codes below the Block Error Rate (BLER) 10−5. Proposed method allows to construct MET QC-LDPC Codes for variable code length with the modular lifting of 5G eMBB Base Graph 2. Simulation results under 50 iterations of sum-product decoding over an AWGN channel with QPSK modulation are provided. It shows near same performance for information length k < 600 and from 0.1 – 0.3 dB gain on k > 600 compared with 5G eMBB codes.
