| 摘 要： | 串行级连卷级码SCCC(Serial Concatenated Convolutional Codes)是近年来提出的一种性能较好的信道编码方式,它由2个串行的反馈系统卷积码RSC(Recursive Systematic Convolutional codes)和一个内交织器构成,其中内交织器起着十分关键的作用.根据SCCC的结构和截位(puncture)方法提出了适用于SCCC的"均衡保护"伪随机S交织器.理论和仿真结果都表明:在SCCC中"均衡保护"伪随机S交织器的性能要远优于其它的随机交织器和分组交织器.总结了SCCC内交织器的设计准则. |

| 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. |
