Abstract:   A common assumption in the study of quantization errors is that the errors in different channels are independent and identically distributed. Using this assumption a Mean Square Error (MSE) estimate is derived. But is the assumption realistic? We present some theoretical studies, as well as extensive numerical data, to show that such an assumption is way off the mark. This is joint work with David Jimenez and Long Wang.
