Abstract

In this paper we investigated methods that increase correlation between two values using one or two bits of extra information. 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 corrections+difference quantization' and '2-bit 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.
