The paper studies the performance of turbo code and the concatenated code which makes up of rs code and convolutional code 本文对rs与卷积级联编码和turbo码的性能分别进行了研究。
Hybrid concatenated convolutional coded modulation ( hctcm ) is studied . performance bound and design criteria of hctcm are given 研究了混合级联卷积编码调制,得到了它的性能限和设计准则。
In chapter 3 , encoder structure and decoder structure and decoding algorithms of hybrid concatenated convolutional code ( hccc ) is studied 第三章研究了混合级联卷积编码的编译码结构、性能限和设计准则。
2 . aiming at the convolutional code with long encoding restriction we adopt the fano sequential decoding algorithm to implement the decoder 2 、针对编码约束度比较大的卷积码,采用fano序列译码算法来实现译码。
The channel coding is one of important topics in communication research , and it usually falls into two classes : block codes and convolutional codes 信道编码是通信领域研究的重要课题之一,其主要分为分组码与卷积码。
