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。
However , the sequential decoding algorithm is not fully developed because of its complication and limited range of application , which lead to relatively few materials particularly in board 而卷积码的序列译码方法因为其硬件复杂度高和应用范围小,并不十分流行,相关的参考文献也很少,尤其在国内,相关的研究非常少。
The iess 309 standard indicates two decoding methods , we focus on the systemic convolutional code with long encoding restriction which is 36 bit and adopt the fano sequential decoding algorithm to implement the decoder 在协议中规定了两种译码的方式,我们主要是针对编码约束度为36的系统卷积码,采用fano序列译码算法来实现其译码,并进行了仿真。
In order to implement the iess 309 standard and sequential decoding for the convolutional codes in satellite digital receiver , we have made a deep research in sequential decoding algorithm and solved some problems on implementing the sequential decoder for convolutional codes 为了实现iess309协议标准,在卫星数字接收机中实现卷积码的序列译码,我们深入的研究了序列译码算法,解决了序列译码器实现的过程中存在的一些问题。
Sequential decoding is a limited memory technique for decoding tree codes. Sequential decoding is mainly used is as an approximate decoding algorithm for long constraint-length convolutional codes.
