This correspondence introduces an approach to the design of channelrobust vector quantizers. Design criteria are derived based ion a new expression for the channel distortion as a function of the codevectors of the quantizer. The introduced framework for design and analysis holds for arbitrary discrete memoryless channels. Simulations demonstrate good performance. The correspondence also presents new results regarding the channel distortion as a function of the index assignment given to the codevectors of a vector quantizer.
