Abstract: The RF transceivers play an important role in the wireless medical monitoring system. Compared to the conventional RF transceiver, the transceiver in medical sensor nodes has more stringent constraints in terms of power consumption, size limitation and the quality of transmission. Digital modulation schemes used in the wireless transceivers plays an important role in the performance of the transceiver. In this paper the Bit error rate (BER) of different digital modulation schemes are compared under AWGN, Rayleigh and Rician fading channels to identify a suitable digital modulation scheme for biomedical application.
Keywords: Probability of error, BER, transceiver, AWGN, Rayleigh, Rician.
