Abstract :
RS (255, 223) is used as the outer code of concatenated system in CCSDS standard and its speed affects the speed of the whole system. This paper designs the decoder in frequency domain and introduces Good-Thomas prime factor algorithm to realize FFT of 255 point and 15 point, which impoves the decoding speed. The flow chart based on DSP is also presented.
