An adaptable joint source/channel coding system based on residual vector quantization (RVQ) is being developed for channels with nonstationary noise characteristics. The system consists of a residual vector quantizer that uses different numbers of stages for different input vectors. The variable rate RVQ used in this adaptable system is designed with a new design process. This design process generates, in general, different encoder and decoder codebooks. The encoder codebooks provide computationally efficient sequential search tree structures, and the decoder codebooks satisfy conditions necessary for joint optimality.<>
