DEMODULATOR FOR CPFSK-MODULATED SIGNALS USING A LINEAR APPROACH TO THE CPFSK SIGNAL

摘要

In a method for demodulating a CPFSK-modulated signal, the n-1-th substitute symbol an-1 which occurs in the linear approximation of the CPFSK is estimated in order to determine an n-th input data symbol dn on which the CPFSK modulation is based. The n-1-th substitute symbol an-1 is in this case estimated on the basis of the previously determined n-1-th input data symbol dn-1.
