In mobile radio communication it often happens that the received signal disappears owing to, for example, fading. If a receiver is used which is based on the coherent detection principle, acquisition of the carrier must consequently be done repeatedly. In order to avoid the loss of information resulting therefrom, non-coherent detection is used in the receiver for angle-modulated carrier signals in combination with a decision criterion which is based on the possible phase trajectories of the demodulated signal.
