<p>The invention relates to a method for demodulating a digitally modulated signal and to a demodulator. According to the method, a signal (S) to be received is mixed essentially to quadrature related I and Q baseband signals. For improving the interference tolerance of the demodulator, for instance, differences (α) between directional angles (β, η) of sequential shifts of a signal point on I/Q plane are measured from the baseband signals and said difference is utilized for decision-making concerning a received symbol.</p> |
