Abstract
The concepts of ordered code-book and the priority of code-vector are proposed is this paper. The statistical properties of a signal are investigated through its coded sequence. Experimental results are presented which provide some insight into the statistical properties of vector quantized sequences. Based on the given concepts and experimental results, a fast search method for the vector quantization of correlated information sources, such as Gauss-Markov sources, is proposed and has shown its efficiency in simulation results.
