【Abstract】 Serial Concatenated Convolutional Codes (SCCC) is a better scheme presented recently for channel coding. This scheme employs two recursive systematical convolutional codes and an inner interleaver, where interleaver design plays an important role. According to coding structure and puncturing patterns of SCCC, an "balance protection" pseudo random S interleaver was introduced. Theoretical and simulation results showed that the proposed interleaver performed better than other random interleaver and block interleaver,and provided the design criteria of inner interleaver for SCCC.更多还原
