In order to realize error-correcting of Quick Response Code, error correction coding theory has been researched. Encoding and decoding of Reed-Solomon have been fulfilled by means of advanced language based on Galois field of GF(28).
According to its character,we propose a novel soft decision metric and also develop a new iterative decoding algorithm, which integrates principles of modulation code detection,soft decision,array code error correction and Turbo code decoding.
To our knowledge, this error indicator is the first TSC 1/3 code error indicator proposed in the open literature.
In this paper, an asynchronous TSC 1-out-of-3 (1/3) code error indicator is introduced that memorizes erroneous 1/3 code inputs 000, 011, 101, 110, 111 with time duration greater than a discrimination time T.
A Totally Self-Checking 1-out-of-3 Code Error Indicator
Comparison of the code error (difference in polar requirement for single-nucleotide codon interchanges) with the coding triplet concentrations in RNA binding sites for eight amino acids shows that these properties are independent and uncorrelated.
The results show that, compared with the legacy method, the proposed method has better auditory similarity, larger information embedding capacity and lower code error rate.
