Cyclic redundancy checks (CRC) are widely used in transmission protocols to detect whether errors have altered a transmitted packet. It has been demonstrated in the literature that CRC can also be used to correct transmission errors. In this paper, we propose an improvement of the state-of-the-art CRC-based error correction method. The proposed approach is designed to significantly increase the error correction capabilities of the previous method, by handling a greater part of error cases through the management of candidate lists and using additional validations. Simulations and results for wireless video communications over 802.11p and Bluetooth Low Energy illustrate the Peak Signal-to-Noise Ratio (PSNR) and visual quality gains achieved with the proposed approach versus the state-of-the-art and traditional approaches. These gains range on average from 1.6 dB to 7.3 dB over Bluetooth Low Energy channels with Eb/No ratio of 10 dB and 8 dB, respectively.

循环冗余校验 (CRC) 广泛用于传输协议中，以检测错误是否改变了传输的数据包。文献中已经证明，CRC 也可用于纠正传输错误。在本文中，我们提出了对最先进的基于 CRC 的纠错方法的改进。所提出的方法旨在通过管理候选列表和使用额外的验证来处理大部分错误情况，从而显着提高先前方法的纠错能力。通过 802.11p 和低功耗蓝牙进行无线视频通信的模拟和结果说明了所提出的方法与最先进的和传统的方法相比实现的峰值信噪比 (PSNR) 和视觉质量增益。 低功耗蓝牙通道上的 dB，Eb/No 比分别为 10 dB 和 8 dB。
