Reed-Solomon (RS) codes are widely used in modern communication and computer systems. Compared with the hard-decision decoding algorithms, the algebraic soft-decision decoding (ASD) algorithm can achieve significant coding gain. Among ASD algorithms, the low-complexity Chase (LCC) decoding has a better performance and lower complexity. In the LCC decoding, 2η test vectors need to be interpolated and...
We present a unique decoding algorithm of algebraic geometry (AG) codes on plane curves, Hermitian codes in particular, from an interpolation point of view. The algorithm successfully corrects errors of weight up to half of the order bound on the minimum distance of the AG code. It is the first decoding algorithm to combine some features of the interpolation-based list decoding with the performance...
Remote education is a new education mode which can train people all over the world by providing teaching videos. This paper presents an efficient error concealment algorithm for H.264, which we use in the decoder of the video player to improve teaching video quality. In the proposed algorithm, first considering the character of teaching video, estimate the error macro block (MB) belongs to foreground...
