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.Show less >
