The concatenated codes are widely used in current communication systems,such as satellite communication systems and WiMAX system.The objective of this study was to present a low complexity iterative soft decoding algorithm for concatenated codes.The concatenation was between a Reed-Solomon(RS)code and recursive systematic convolutional(RSC)code.The reduction in computational complexity was achieved by simplifying the Chase-2 decoder for RS codes with limited usage of test patterns.The processing of soft information between inner and outer decoders was also discussed.Simulation results showed that the proposed algorithm could achieve a good trade-off between complexity and performance. 展开更多
