ABSTRACT:
A vector quantization me employs mirrored input vectors to increase the reproduction quality of transmitted vector quantized data. A codevector is selected from a vector quantization codebook for each possible orientation of an input vector. The codevector having the smallest distortion relative to the input vector is selected for transmission. An identification code identifying the selected orientation is also transmitted.
