| Abstract | Medical sector has been developing with new technologies. WBAN(Wireless Body Area Networks) is a new treating method for the medical problems. WBANs can be categorized as in body channel and on body channel. Dual mode communication system can receive both in body and on body signals from different transmitters to a single receiver. In body channel has path losses as signal transmit through tissues in the human body. On body transmitter and receiver located on the body surface with a lossy channel as signal transmit through air interface. For in body and on body transmission AWGN and Shadow fading effect reduce the performance of the signal. Change in the transmit power and bandwidth can vary the performance of each channel according to the channel modulation technique. Transmit power and bandwidth must be within a limit without any harm to the human body in a realistic model. The performance of each model with AWGN and shadow fading can vary with QPSK , BPSK and PPM modulation techniques. The performance evaluation for each modulation was done by a MATLAB simulation. By changing the parameters for in body and on body communications such as increasing the transmit power to plot each scenario for BANs AWGN and shadow fading channels was done through simulation until simulation gives better performances. The comparison of each plot for different modulation techniques leads to obtain the better performance for in body and on body models. This project concludes by obtaining the better performance from QPSK(Quadrature Phase Shift Keying) modulation technique. |
