Abstract:
A technique for determining in a fading channel environment a scaling factor for soft bit quantization is proposed. In a method realisation, the technique includes repeatedly determining an SNR value for the fading channel, calculating a weighted average based on a plurality of the SNR values, wherein weighting is performed such that contributions of extremal SNR values are attenuated, and determining the scaling factor for soft bit quantization dependent on the weighted average.
