Petri提出了超正交卷积Turbo码(superorthogonal Convolutional Turbo Code,SCTC)。由于带宽的扩展,这类码的性能比一般的Turbo码好。本文推导了一般SCTC码的构造,同时导出了存储单元分别为2,3的SCTC的转移函数。分别给出了高斯信道下和非相关瑞利衰落信道下SCTC码的误码率性能上限,以及计算机模拟的高斯信道、非相关瑞处衰落信道和相关瑞利衰落信道下的SCTC码的误码率性能。
Petri proposed a superorthogonal convolutional turbo code (SCTC). Due to the expansion of bandwidth, the performance of this type of code is better than the average Turbo code. This paper deduces the construction of general SCTC codes and derives the transfer function of SCTC with memory cells 2 and 3, respectively. The upper bound of the bit error rate (BER) of SCTC codes under Gaussian channels and non-correlated Rayleigh fading channels are given respectively, and the errors of the computer simulation of Gaussian channels, non-correlated RBS fading channels and SCTC codes under correlated Rayleigh fading channels Rate performance.
