METHOD AND APPARATUS FOR REAL-TIME DEMODULATION OF A GMSK SIGNAL BY A NON-COHERENT RECEIVER

摘要

The GMSK real-time demodulation apparatus and pro-cess of the present invention demodulates a coherent quadra-ture phase modulated GMSK signal in real-time using a non-coherent receiver. The GMSK signal is initially non-coher-ently detected, thus producing a channel symbol signal. Thissignal is then differentially decoded to recover the encoded dig-ital information.
