Abstract
A method for recovering data included in a digitally modulated signal is described. The digitally modulated signal includes a symbol sequence. The method includes providing a mathematical model of the digitally modulated signal, the mathematical model describing the digitally modulated signal in terms of the symbol sequence and describing the digitally modulated signal in terms of a step response and/or an impulse response, and wherein the mathematical model also takes disturbances into account; and processing the digitally modulated signal based on the mathematical model, thereby recovering the data included in the digitally modulated signal. The disturbances include a random disturbance component modelled as a Gaussian disturbance, and include an inter-symbol interference component modelled as Gaussian noise, and wherein a dependence of the at least one step response on the symbol sequence is neglected within the mathematical model. Further, a measurement instrument and a measurement system are described.
