Advanced intermediate frequency zero-crossing detection of bandpass filtered MSK signals
Tobias Scholand, Peter Jung · Electronics Letters · 2003
Short range communication systems such as Bluetooth deploy Gaussian frequency shift keying modulation which has been derived from minimum shift keying (MSK). The authors present and analyze an improved zero-crossing detector for MSK signals called a zero-crossing decorrelation detector. The impact of bandlimitation is taken into account.
