摘要:
A device for scaling and quantization of digital soft output values (sk) from an equalizer has a control loop for controlling a statistical parameter (θ) for the scaled and quantized soft output values (sD,k), which contains a calculation unit (4) for calculation of the statistical parameter (θ), and a control unit (5) for calculation of a scaling factor (c) for scaling the soft output values (sk) from the equalizer on the basis of the statistical parameter (θ).
