title: Design of trellis coded vector quantizers using Kohonen maps.
abstract: Although the performance of trellis coded vector quantizers (TCVQs) is much better than that of conventional memoryless vector quantizers, designing the trellis in TCVQs has a certain amount of computational overhead. In this paper, we apply Kohonen maps to simplify the design process of the TCVQs by exploiting the ordering property of Kohonen maps. This new implementation of the TCVQs is named as trellis coded Kohonen maps (TCKMs). Simulation results show that, with such a simple design process, the performance of the TCKMs is still comparable to that of the conventional TCVQs.
