ABSTRACT
In order to reduce the error caused by the noise in communication channel， the error control encoding technology will be necessary to be introduced before sending the digital message to channel in order to make the interference to the lowest point.The error control encoding technology to improves the error rate， enhances the correspondence the reliability to have the vital role. I pass through in the project practice study (7，3，4) Hamming code， and under teacher's instruction， adds through own innovation to the improvement， causes it not only to be allowed stochastically to correct to be wrong， but also may correct two burst errors This principle will study which according to me I have written the error correction ability stronger decoding circuit in the graduation project， they have the greatly strengthened error correction ability， can correct the multi- positions the burst error， will receive the widespread use in the communications system. This article introduced the use logic circuit， in the max+plusII platform， uses the FPGA realization confirmation use for (15，7，5) the cyclic code improvement innovation re-engineering， enables its to investigate (15，7，5) in the code to seven all burst errors new decoder design method， finally lists the complete design paper and its the succession simulation movement result.
