위성망에서 효율적인 순방향 에러정정 기법 = Effective FEC for Satellite Network

다국어 초록 (Multilingual Abstract)

In this paper, a new method of FEC(Forward Error Correction) using multi-stage Viterbi coder is proposed, with effectively reduce BER in satellite ATM Networks.
In terms of structural complexity, proposed multi-stage Viterbi coder simpler than the traditional single-stage coder based on the same BER performances. And, through simulation, proposed coder shows excellent error correction capabilities compared with traditional FEC schemes.
Also, we propose a selective FEC mechanism that adaptively changes the number of stages to satisfy the QoS(Quality of Service) requirements. This Selective scheme can be easily implemented using the PLCP(Physical Layer Convergence Protocol) frame structure.
