In this paper we investigate the frame-error correcting performance of two newly developed, non-binary belief propagation based, soft-in/soft-out decoding algorithms when decoding Reed-Solomon codes. We present results for the AWGN channel indicating that non-binary belief propagation can come close to the performance of the binary adaptive Belief- Propagation algorithm or even slightly better when decoding short Reed-Solomon codes.
