摘要
En 中文
Interlayer interaction of a layered error-recovery mechanism to act against channel errors for wireless-data communications is examined in this paper. Error-control designs are implemented at two different layers in the protocol stack. A finite number of retransmissions is performed at the lower layer by a mix-mode automatic-repeat request as the primary error removal. At the upper layer, a time-out mechanism is employed, together with a packet-level coding technique, as the secondary error elimination. Performance of the proposed scheme is analyzed and verified by simulations. Through numerical experiments, we have demonstrated how the system performance is influenced by layer parameters. It is discovered that error-correcting capability needs to function at the upper layer to ensure a good system performance.
