摘要

作者研究了基于单个函数f的网格编码调制(TCM)的解析表示的一些特征。他们首先考虑函数f的结构，并观察到(i)它必须是非线性的，(ii)它可以反映编码的某些相位不变性，(iii)它可以反映编码器的内在并行结构。然后，他们给出了基于正交Volterra级数的f的一般参数表示，并给出了一些具有码间干扰的信道的编码设计示例

On the analytical representation of trellis codes

The authors examine some of the features of an analytical representation for trellis-coded modulation (TCM), based on a single function f. They first consider the structure of the function, f, and observe that (i) it must be nonlinear, (ii) it can reflect certain phase-invariance properties of the code, and (iii) it can reflect the intrinsic parallel structure of the encoder. Then they provide a general parametric representation of f based on orthogonal Volterra series, and show some examples of code design for channels with intersymbol interference.<>
