摘要

提出了一种用于ADSL系统的低复杂度M-D(多维)TCM解码器VLSI架构。我们通过修改整个解码过程，使用了共享子集解码器模块。此外，我们还采用了MSA(模块集面积)运算，消除了四维度量计算中的乘法运算，提高了解码速度。因此，该解码器减小了芯片面积，可用于高速xDSL系统。

A low-complexity VLSI architecture of multidimensional TCM decoder for ADSL

We propose a low complexity M-D (multidimensional) TCM decoder VLSI architecture for ADSL System. We use the shared subset decoder module by modifying the whole decoding procedure. Also we improve the decoding speed by using the MSA (module set area) operation, which removes multiplication in 4D metric calculation. So the proposed TCM decoder reduces chip area and can be adopted in high-speed xDSL system.
