摘要： The invention relates to a method in signal processing for quantizing likelihood quotients of binary random variables for transmitting between at least two signal processing units. Decision levels and reconstruction levels of a quantization of likelihood quotients are thereby determined by maximizing (10) corresponding information between the binary random variables and the associated quantized likelihood quotients at a prescribed probability distribution of the likelihood quotients. The invention further relates to a corresponding quantization device. For the quantization device, means are provided for determining decision levels and reconstruction levels of a quantization of the likelihood quotients by maximizing the corresponding information between the binary variables and the associated quantized likelihood quotients at a prescribed probability density of the likelihood quotients.
