Abstract :
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
