The receiver with message propagation (MP) decoder algorithm realises the decoding of traditional Luby transform (LT) encoded packages when there is only one unknown packet adjacent to the encoded package. Error packets can be recovered by decoding with jointing product code composed of shifted Luby transform (SLT)‐encoded package and error packets. In this study, error correction scheme based on single feedback of SLT‐encoded package was adopted for the recovery of received partial error packets over the erasure channel. The scheme of an MP decoder with an error correction code was proposed, and expand shifted robust soliton distribution (ESRSD) appropriate for the scheme feature was designed. Experimental results indicate that the scheme effectively improves the efficiency of the decoder. Compared with the traditional shifted robust soliton distribution, the ESRSD has better decoding performance for the LT code.
