| Abstract: | In order to resolve the problem that the great consumption of hardware resources of pre-decoding method,it is analyzed theoretically first,and then a set of optimized decoding arithmetic is brought out to decrease the hardware cost to an acceptable level.According to the above precept,experimental data based on Golay code with Quartus II has been put out in evidence for the feasibility and validity of that method. |
