Abstract :Dual carrier modulation insert ignore into journalissuearticles values(DCM); using orthogonal frequency-division multiplexing insert ignore into journalissuearticles values(OFDM); improves the performance in multipath fading channels. In the literature DCM is proposed with 16-quadrature amplitude modulation insert ignore into journalissuearticles values(16QAM); for ultra-wideband insert ignore into journalissuearticles values(UWB); communication, with four bits per symbol to keep reliable high date transmission over longer distances. Body area network insert ignore into journalissuearticles values(BAN); standards address transmission reliability more than data rate. UWB is one of the physical layers proposed in BAN standards. In this study, DCM is used with quadrature phase shift keying insert ignore into journalissuearticles values(QPSK); instead of 16QAM to have better performance in reliable transmission. The performance of QPSK-DCM is analyzed and compared with 16QAM-DCM, QPSK-OFDM, and 16QAM-OFDM in a wireless body area network channel. These simulation results are given as bit error rate insert ignore into journalissuearticles values(BER); versus signal to noise ratio per bit insert ignore into journalissuearticles values($E_b/N_0$); graphs. Additionally, derivations of theoretical $BER-E_b/N_0$ performances of QPSK-OFDM and 16QAM-DCM in an additive white Gaussian noise insert ignore into journalissuearticles values(AWGN); channel are given.
