Error correction block based ARQ protocol for wireless digital video transmission

This paper proposes a new error correction block based hybrid ARQ protocol, in which physical layer packets are formed with the use of multiple error correction blocks, and the retransmission control is performed on the basis of these error correction blocks. This protocol is designed dedicatedly for mobile AV stations to provide high quality digital video transmission through a radio channel. To analyze the performance of this protocol, numbers of asymptotic and simulation values of the frame loss rate versus the uncorrectable error probability are calculated, in comparison with the performance of the ordinary packet based retransmission control.
