在这封信中，我们提出了一个自适应SC（连续取消）列表解码器的极性码与CRC。这种自适应SC列表解码器迭代地增加列表大小，直到至少一个生存路径可以通过CRC。仿真结果表明，自适应SC列表解码器提供了显着的复杂度降低。我们还证明，极化码（2048，1024）与24位CRC解码由我们提出的自适应SC列表解码器具有非常大的最大列表大小可以实现误帧率FER
In this letter, we propose an adaptive SC (Successive Cancellation)-List decoder for polar codes with CRC. This adaptive SC-List decoder iteratively increases the list size until at least one survival path can pass CRC. Simulation shows that the adaptive SC-List decoder provides significant complexity reduction. We also demonstrate that polar code (2048, 1024) with 24-bit CRC decoded by our proposed adaptive SC-List decoder with very large maximum list size can achieve a frame error rate FER
