Demodulating system for MSK and GMSK signal using a fast fourier transform converter

A demodulating system for estimating frequency offset and sampling time error by a Fast Fourier Transform operation, which receives a modulated signal sent from a GMSK (Gaussian Low-Pass Filtered Minimum Shift Keying) or a MSK (Minimum Shift Keying) transmitter and demodulates the signal. The demodu...

Zusammenfassung:	A demodulating system for estimating frequency offset and sampling time error by a Fast Fourier Transform operation, which receives a modulated signal sent from a GMSK (Gaussian Low-Pass Filtered Minimum Shift Keying) or a MSK (Minimum Shift Keying) transmitter and demodulates the signal. The demodulating system uses a Fast Fourier Transform converter to obtain frequency offset and sampling time error by applying to it an initial demodulated result generated from a discriminator or a phase differentiator.
