Abstract: - We study the use a continuous phase modulation (CPM) system providing mobile data service withQPSK transmission for a telemedicine system. The results of using an I/Q modulation and CPM schemes withtheir BER performance are compared. The system provides direct symbol-by-symbol detection with no specialdecoding mechanism necessary. We have compared the performance in bit error rate (BER) with coherentdetection of CPM and I/Q modulation. The scheme offers high bandwidth and power efficiency making itparticularly suitable for telemedicine applications.
