Abstract A multicast error control scheme which takes advantage of both MDS codes and GMD decoding is proposed and analyzed. The proposed scheme is characterized as follows: 1. The sender does not retransmit data frames. The frames to be retransmitted consist of the redundant symbols obtained by encoding the previously transmitted data frames. 2. Each receiver stores erroneous frames not greater than the prearranged number and decodes them all of a lump using the retransmitted frames of the fixed number. Numerical results show that the proposed scheme yields higher throughput not only for the case where the bit error rate is very large but also for the case where the number of VSATs is very large.
