Abstract
The authors analyse a new topology for designing ring-TCM schemes over N-di mensional constellations. The squared free distance of these codes is optim ised, thus optimisation is performed for AWGN channels. The generalised top ology is studied for M-PSK and N-dimensional constellations. An improvement is obtained by using an N-dimensional constellation, in comparison with it s M-PSK constellation counterpart. This improvement is more evident for hig her level constellations.
