摘要

我们展示了终止递归系统卷积编码器的系统组件提供了内置的CRC(循环冗余检查)，并且我们使用该特性来提高平均符号变化(MSC)准则的性能。此外，我们还表明，通过将外部短CRC与MSC标准连接起来，可以进一步提高错误检测性能。

Improved performance of error detection in turbo decoding by incorporating a short CRC with the mean-sign-change criterion

We show that the systematic component of a terminated recursive systematic convolutional encoder provides a built-in CRC (cyclic redundancy check), and we use this characteristic to improve the performance of the mean-sign-change (MSC) criterion. In addition, we show that by concatenating an external short CRC with the MSC criterion the error detection performance can be improved even further.
