Abstract :
This work proposes a reconfigurable adaptive FEC system. For adaptive FEC schemes, we can implement an FEC decoder which is optimal for error correction capability (t) by taking the number of operations into consideration. Reconfiguring the optimal FEC decoder dynamically for each t allows us to maximize the throughput of each decoder within a limited hardware resource. Our system can reduce packet dropping rate more efficiently than conventional fixed hardware systems for a reliable transport protocol.
