咬尾卷积码的误差网格构造

Error-Trellis Construction for Tailbiting Convolutional Codes

Masato Tajima, Koji Okino

摘要:

在本文中,我们提出了一个错误网格构造咬尾卷积码。咬尾错误网格的特征在于伴随子形成器在相同状态中开始和结束的条件。我们澄清了代码子网格的咬尾代码网格和错误子网格的咬尾错误网格之间的对应关系。此外,我们提出了一种构造咬尾向后误差网格。此外,我们还得到了咬尾卷积码的标量校验矩阵。所提出的结构是基于伴随的显式实现的一个综合征前和它的行为是充分利用的讨论。

英文摘要:

In this paper, we present an error-trellis construction for tailbiting convolutional codes. A tailbiting error-trellis is characterized by the condition that the syndrome former starts and ends in the same state. We clarify the correspondence between code subtrellises in the tailbiting code-trellis and error subtrellises in the tailbiting error-trellis. Also, we present a construction of tailbiting backward error-trellises. Moreover, we obtain the scalar parity-check matrix for a tailbiting convolutional code. The proposed construction is based on the adjoint-obvious realization of a syndrome former and its behavior is fully used in the discussion.
