| Abstract: | Studies synchronization design theory of GMSK demodulation for GSM digital landmobile radio system. The nonlinear GMSK signal can be approximated by a linear offset QAMsignal.The theoretical calculation of the correlation synchronization technique is solved.Acomputer simulation has been presented to study the performance of GMSK MODEM. Thesvnchronization of GMSK demodulation is realized by hardware. Then,the svnchronization de-sign has been proved to be correct. |
