Abstract

In this paper we investigated methods for designing side information of multiple description coding when transmitting two values independently. For methods that use one bit, we investigated '1-bit quantization,' 'sign correction' and 'difference quantization' methods. For those that use two bits, we investigated '2-bit quantization,' 'sign correction+difference quantization' methods. From theoretical analysis and numerical experiments, it has been found that the quantization-based method is best when correlation of the original data is weak, while 'difference quantization' or combination of sign correction is better when the original data have strong correlation. Then we applied the methods to multiple description coding of speech signals.
