论文摘要
我们在某些5G新广播（NR）部署方案中使用无前缀代码分布匹配（PCDM）进行速率匹配（RM），以0.2位/符号的细粒度，实现了从1.4到6.0位/符号的广泛信息速率。我们研究了基于PCDM的RM的性能和实施，与5G NR标准中定义的基于低密度平价检查（LDPC）的RM相比。加性白色高斯噪声通道中的仿真表明，与测试的情况下，基于PCDM的RM可以以10-2的块错误速率获得信噪比的2.16 dB增益，而在测试的情况下，可以以较小的硬件成本以基于LDPC的RM而获得。
We use prefix-free code distribution matching (PCDM) for rate matching (RM) in some 5G New Radio (NR) deployment scenarios, realizing a wide range of information rates from 1.4 to 6.0 bit/symbol in fine granularity of 0.2 bit/symbol. We study the performance and implementation of the PCDM-based RM, in comparison with the low-density parity-check (LDPC)-based RM, as defined in the 5G NR standard. Simulations in the additive white Gaussian noise channel show that up to 2.16 dB gain in the signal-to-noise ratio can be obtained with the PCDM-based RM at a block error rate of 10-2 when compared to LDPC-based RM in the tested scenarios, potentially at a smaller hardware cost.
