A received binary signal is sampled with different thresholds, the sampling results are integrated and stored. The device includes a chamber, through which the first medium flows and inside which at least one mass-permeable andor energy-permeable hollow fiber, preferably a plurality of mass-permeable andor energy-permeable hollow fibers, is are arranged. The control system includes a feedback loop for each drive unit feeding a drive unit feedback signal including at least the actual value of one operational parameter of the respective drive unit back to the controller. The processor determines cross-correlations between symbol waveforms from different symbols and multiple paths.
