碩士 === 中原大學 === 電子工程研究所 === 101 === Soft-decision decoding of Reed-Solomon (RS) code can improve the decoding performance significantly, but the system complexity is high. Therefore, most of the communication systems use the hard-decision decoder because of low complexity. However order statistic decoding algorithm (OSD) is an effective decoding algorithm which can reduce the complexity of the system. In this thesis, we used a non-binary OSD algorithm which can be applied to non-binary RS code. We also consider different ways of computing symbol reliability and decoding metric in the proposed algorithm. Besides, we proposed several ways to reduce the system complexity. Simulation results show the performance of the algorithm under partial band noise jamming (PBNJ) and AWGN.
