A Continuous Phase Modulation Scheme for Telemedicine Systems

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