The invention relates to a method for demodulating a received signal relating to a sequence of transmitted symbols that have been modulated by continuous phase modulation, the method comprising the steps of: 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. The invention further relates to a receiver for demodulating a received signal relating to a sequence of transmitted symbols that have been modulated by continuous phase modulation.

Abstract

The invention relates to a method for demodulating a received signal relating to a sequence of transmitted symbols that have been modulated by continuous phase modulation, the method comprising the steps of: 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. The invention further relates to a receiver for demodulating a received signal relating to a sequence of transmitted symbols that have been modulated by continuous phase modulation.
