Abstract
A two-stage vector quantizer-lattice vector quantizer (VQ-LVQ) is introduced. Due to the relative ease of lattice vector quantization, the joint optimum encoding is feasible for moderate-to-large encoding rates and vector dimensions. The VQ-LVQ is comparable or superior to equivalent-delay encoding results reported for memoryless sources. Some simulation results are presented for memoryless Gaussian sources
