摘要

A pseudo-random synthesized signal is provided by analysis of a plurality of related signals by vector quantization of linear predictive coding coefficients (cluster representatives) of time blocks of the signals and providing cumulative probability matrices for the transition from one cluster representative for one block to a cluster representative of the next successive block of each of the signals. Synthesis of the pseudo-random signal is provided by randomly selecting according to a cumulative transition probability, the cluster representative of a next successive block given the selected cluster representative of the previous block, the coefficient of each block time being applied to a noise-excited recursive filter to generate the pseudo-random synthesized signal.
