文摘
Wireless body area networks (BAN) are primarily being designed for the detection of diseases and tracking of patients on the move. Due to its low-power requirements, ultra-wideband (UWB) has become the most preferred candidate for the physical layer of BAN. However, UWB suffers from the interferences from existing wireless networks. Again, the interference mitigation techniques developed for UWB will not be feasible for BAN because of their complexity and resulting power consumption. In this paper, we have proposed a hybrid Hermite pulse for cancelling multiple narrowband interferences. A comparison of the proposed technique with existing techniques is presented based on the operations count that highlights the lower complexity of the proposed technique. The proposed technique is also compared to Gaussian pulse based hybrid pulse in the simulation section to prove its superiority. Mathematical and simulation results prove that besides being of lower complexity the technique can mitigate the interferences satisfactorily.
