Yongjun Zhang · 2012
This paper researches and analyzes the national standard of QR Code and the characteristics of systematic form of Reed-Solomon (RS) codes in QR Code. Furthermore, RiBM algorithm, Chien search algorithm and Forney algorithm are applied to implement Reed-Solomon algorithm. consequently, the computational complexity of RS error-correcting decoding is reduced and the decoding speed of QR Code is improved.
