The Design of a RS Encoder

Based on the GF (28) polynomial multiplication principle, the conventional Reed-Solomon (RS) coding structure is used to implement the RS(255,223) encoder from CCSDS(Consultative Committee for Space Data System) 131.0-B-1 suggestion. The remainder program of polynomial multiplication and the test method of RS encoder are described. Analysis of the simulation and implementation results of the encoder on Xilinx FPGA Vc4sx55 are given. The results indicate that the encoder is highly efficient and suitable to high speed data transmission for the satellite downlink in coding rate of 395Mbps.
