Abstract
A method for demodulating a received signal relating to a sequence of transmitted symbols that have been modulated by continuous phase modulation includes normalizing samples of a sequence of samples generated from the received signal, to obtain a normalized sequence of samples, wherein an amplitude of each sample of the normalized sequence of samples has an absolute value equal to unity; estimating, on the basis of the normalized sequence of samples, a time offset and a frequency offset of the received signal, and using the estimated time offset and the estimated frequency offset for compensating the normalized sequence of samples for the time and frequency offsets, to obtain a compensated sequence of samples; and determining a sequence of symbols corresponding to the transmitted sequence of symbols on the basis of the compensated sequence of samples. Also disclosed is a receiver for demodulating a received signal relating to a sequence of transmitted symbols that have been modulated by continuous phase modulation.
