Abstract

The parameters and decoder algorithm of RS(204,188) according to DVB-H specification is introduced.It is given that the reformulated inversionless algorithm which is used to solve the key equation.The decoder based on this algorithm is designed and implemented with Verilog HDL.As test results shown,decoder described in this paper decrease resource usage in a great deal at high speed.
