论文摘要
在本文中，我们采用卷积代码的线性系统表示来开发用于擦除通道的卷积代码的解码算法。我们使用状态空间描述研究解码问题，并以自然方式提供其他信息。关于以前已知的解码算法，我们的新算法具有一个优势，即它能够减少解码延迟以及擦除恢复过程中的计算工作。我们描述了卷积代码应具有哪些属性，以便获得良好的解码性能并以示例进行说明。
In this paper, we employ the linear systems representation of a convolutional code to develop a decoding algorithm for convolutional codes over the erasure channel. We study the decoding problem using the state space description and this provides in a natural way additional information. With respect to previously known decoding algorithms, our new algorithm has the advantage that it is able to reduce the decoding delay as well as the computational effort in the erasure recovery process. We describe which properties a convolutional code should have in order to obtain a good decoding performance and illustrate it with an example.
