Abstract
A method is provided for evaluating a first time-domain signal received from a single source, wherein the time domain signal is processed with a Fourier-related transform with overlapping input frames to provide a first frequency-domain signal being made up of frames of coefficients, wherein only one part is included in the first frequency-domain signal, wherein a first part is the part, real or imaginary, that is included in the frequency-domain signal and a second part is the part, real or imaginary, that is not included in the frequency-domain signal. The method is performed by a signal evaluator. The method comprises: receiving the first frequency-domain signal; obtaining a reference frequency-domain signal; and determining a first cross-correlation between the received first frequency-domain signal and the reference frequency-domain signal by cross-correlating the received first frequency-domain signal and the reference frequency-domain signal.
