Device and method for control scaling and quantization of soft output values from an equalizer

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 (&thetas;) for the scaled and quantized soft output values (sD,k), which contains a calculation unit (4) for calculation of the statistical parameter (&thetas;), 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 (&thetas;).
