The Half-t adaptive error correction algorithm for SDH-based WDM optical networks


Cheah, Cheng Lai and Abdullah, Mohamad Khazani (2007) The Half-t adaptive error correction algorithm for SDH-based WDM optical networks. In: IEEE International Conference on Telecommunications and Malaysia International Conference on Communications (ICT-MICC 2007), 14-17 May 2007, Penang, Malaysia. (pp. 175-180).


This paper proposes an adaptive forward error correction (FEC) algorithm, referred to as the Half-t algorithm for synchronous digital hierarchy (SDH) based wavelength division multiplexing (WDM) optical networks. Unlike most previous adaptive FEC algorithms which change to a stronger code for error correction based on either packet losses or erroneous condition, the Half-t algorithm is able to do so before an error occurs. Simulation results show that the Half-t algorithm can maintain the output bit error rate (BER) below a target BER by assigning an appropriate value of waiting delay before changing to a weaker code.
