A statistical model for product quantization where the error made by rounding a product is considered a discrete random variable is presented. The mean square of the error in the output due to product quantization is found. The model considers the effects of using different quantization levels for the input, coefficients, and products. A comparison to the results obtained using the usual continuous random variable model is made.
