ABSTRACT:
A demodulator (6) for demodulating a modulated signal (3) comprises a Hubert transformer (7) for generating a Hubert transformed modulated signal (18) of the modulated signal (3). The Hubert transformed modulated signal (18) comprises modulated (5) and unmodulated signal sequences (4) and originates from an unmodulated signal. The demodulator (6) further comprises a comparing device (14) for comparing the Hubert transformed modulated signal (18) with a reference signal (15), which corresponds to the Hubert transformed unmodulated signal. The demodulator (6) is further configured to identify the modulated and unmodulated signal sequences (4, 5) based on the comparison.
