摘要:
为减少在实际的硬件实现过程中极化码连续删除(SC)译码由于自身硬件因素引发的译码错误,构造了一个简单的基于二进制删除信道(BEC)的故障模型,在该模型下在任何码元速率下都不可能实现完全可靠的通信。针对此故障模型,提出了一种非均匀错误保护方案,并通过仿真验证,表明该方案在可忽略的硬件开销的情况下,显著地改善了连续删除译码在故障二进制删除模型下的译码性能。
Abstract:
In order to reduce the decoding errors caused by hardware factors about polar codes successive cancellation (SC) in the process of actual hardware implementation, a simple fault model based on the binary erasure channel (BEC) was built. In this model, it is impossible to achieve complete and reliable communications at any rate. For this fault module, a non-uniform error protection scheme was proposed, and the simulation shows that the scheme can be ignored in hardware cost, which significantly improves decoding performance of successive cancellation decoding by the fault binary erasure model.
