Abstract:
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.
Abstract:
There is provided a system and method for multi-user detection by a plurality of base stations situated at different geographical locations through base station cooperation. An exemplary method comprises exchanging detected data iteratively while performing separate detection and decoding of received data streams.
