The minimum weight deceding algorithm for Reed-Solomon cedes is discussed,based on acombination of preriousiy known error- trapping and trial- and -error decoding techniques. It isrelatively simple , work-efficient and particularly suitable for the Reed-Solomon codes with largeerror-correcting capability, because it exploits the inherent structure of the cyclic cedes for which it isintended.As an example, a parallel decoder for Reed-Solomon(15,9,3 ) code is developed,itstransfer rate is over 10 Mbits/s.
