Optimizing redundancy for the encoding method including Fountain code and RS code. a The error rate was simulated by DeSP and guided the adjustment of parameter α and \({L}_{RS}\). b The target optimization parameter α determines how many extra sequences are generated when encoding with the fountain code. The parameter \({L}_{RS}\) is the length of the RS code
