| Abstract: | For getting the coding performance close to LLR algorithm, the simple correlation operation with the output of the decoder was carried out, and the Chase2 decoding algorithm was modified. By receiving information with the soft information of the sub-decoder output, the turbo iterative decoding of parallel concatenated block code was realized. Simulation results show that this algorithm is valid. |
| Keywords: | parallel concatenated block code iterative decode chase decoding algorithm correlation operation linear superposition |
