Device and method for the controlled scaling and quantization of soft - output - values of an equalizer

摘要

The invention relates to a device for scaling and quantization of digital soft - output - values (s φ k φ) of an equalizer. The device has a control loop for controlling a statistical parameter (theta) of the scaled and quantized soft - output - values φ (s d, k φ), which a calculation unit (4) for the calculation of the statistical parameter (theta) and a control unit (5) for calculating a scaling factor (c) for the scaling of the soft - output - values (s φ k φ) of the equalizer with the aid of the statistical parameter (theta) contains.
