Abstract：The traditional lookup table decoding algorithm and the improved lookup table decoding algorithm for BCH code are introduced is this paper.The(15,5,7)BCH code is used as an example,the decoding performances of the triple-error-correct-ing BCH code based on these two algorithms are compared.Based on the improved lookup table decoding algorithm,a FPGA-based (15,5,7)BCH code decoder is designed.The results of the research show that the improved algorithm is characterized by low re-sources cost and high decoding speed relative to the traditional algorithm.The design scheme of the decoder based on the improved algorithm features has simpler structure,smaller device utilization coast and faster speed,and it is easy for project implementation.
