Abstract:
Multiple-description coding is one way to gain robustness against lossy channels. We extend
the multiple-description scalar quantizer (MDSQ) to a channel-optimized MDSQ (COMDSQ) that
minimizes mean-squared error for a given channel environment. We discuss necessary and sufficient
conditions for the optimality of M-channel COMDSQ’s and provide procedures for the design of
2-channel COMDSQ’s. We provide example results including audio files from waveform and transform
coders that employ COMDSQ’s.
