摘要：

A concatenated coding scheme is proposed in this paper, which uses Reed-Solomon (RS) product code for outer code and convolutional code for inner code. The interleaving pattern, which is generated according to congruential sequence, is used to rearrange the symbols of RS product code. The iterative decoding of the concatenated coding scheme is based on the soft decoding of the component codes. When a given maximun number of iteration has been performed, a method is proposed to correct residual errors by computing the syndromes of RS codes. The simulation results show that coding gains up to 0.4 dB for a BER (Bit Error Rate) is of 1e-5 on the Gaussian channel comparison with concatenation RS/CC codes.
