查询词典 concatenated

In chapter three, the author studies channel coding and decoding techniques, that is Woven codes. On the basis of other researchers'results, the author presents a four-port soft input and soft output module, in order to facilitate iterative decoding process of concatenated codes. This module is not only suit for decoding a concatenated code with non RSCs as its constituent codes, but also it can provide soft information output of both codeword and information bits, so it can be applied to decoding a Turbo code and joint detection and decoding. Taking into consideration serial and parallel concatenated Turbo code, the author proposes a combined code, with 2 outer codes and 2 inner cods as its constituent codes, i.e., 2×2 Woven code.
