摘要：The error rate of error correcting codes with soft-decision-decoding rarely has a closed-form expression. Bounding techniques are widely used to evaluate the performance of maximum-likelihood decoding algorithm. But the existing bounds are not tight enough especially for a low signal-to-noise ratios region and become looser when a suboptimum decoding algorithm is used. The radius of decision region is applied to evaluate the word error rate (WER) of error correcting codes with different decoding algorithms. Simulation results show that this method can effectively evaluate the WER of different decoders with 0.05dB maximum error .
